The ultrasonic medical detection device 100 shown in FIG. 1 mainly includes: a probe 101 , a transmitting circuit 103 , a transmitting/receiving selection switch 102 , a receiving circuit 104 , a beam forming module 105 , a signal processing module 116 and an image processing module 126 . During the ultrasonic imaging process, the transmitting circuit 103 transmits the delayed and focused transmit pulses with a certain amplitude and polarity to the probe 101 through the transmit/receive selection switch 102 . The probe 101 is excited by the emission pulse, and emits ultrasonic waves (which can be any one of plane waves, focused waves, or divergent waves) to the detection object (eg, organs, tissues, blood vessels, etc. in the human body or animal body, not shown in the figure). ), after a certain delay, the ultrasonic echo with the information of the detection object reflected from the target area is received, and the ultrasonic echo is re-converted into an electrical signal. The receiving circuit 104 receives the electrical signals converted and generated by the probe 101 , obtains ultrasonic echo signals, and sends these ultrasonic echo signals to the beam forming module 105 . The beam forming module 105 performs focusing delay, weighting and channel summation on the ultrasonic echo signal, and then sends the ultrasonic echo signal to the signal processing module 116 for related signal processing. The ultrasonic echo signal processed by the signal processing module 116 is sent to the image processing module 126 . The image processing module 126 performs different processing on the signals according to the different imaging modes required by the user to obtain ultrasound image data of different modes, and then processes such as logarithmic compression, dynamic range adjustment, and digital scan conversion to form ultrasound images of different modes. Such as B images, C images, D images, etc., or other types of two-dimensional ultrasound images or three-dimensional ultrasound images. The above-mentioned transmitting circuit and receiving circuit excite the probe to transmit an ultrasonic beam to the detection object according to the setting of the ultrasonic imaging parameters, and receive the echo of the ultrasonic beam to obtain the ultrasonic echo signal, thereby obtaining the desired ultrasonic image data for display and presentation.

Implemented on a processor/controller chip.

The obtained ultrasound image can be output to the first touch display screen 130 for display. The first touch display screen 130 is connected with the image processing module through an input and output interface (the input and output interface can be implemented by wired communication or wireless communication) to realize data transmission. In addition, the first processor 140 and the first memory 160 may also be included. The first processor 140 invokes the computer program instructions recorded on the first memory 160 to display the ultrasound image on the first touch display screen 130 and/or form a graphical user interface on the touch screen display. In one of the embodiments, a graphical user interface (GUI) is displayed on the first touch display 130 and displays graphical controls such as the aforementioned ultrasonic imaging parameter adjustment and various function keys involved in the ultrasonic imaging process.

In some of these embodiments of the invention, the user interacts with the graphical user interface primarily through gesture input on the touch display screen. Gesture input here may include any type of user gesture input that the device can detect through direct contact with the touch display or proximity to the touch display. For example, the gesture input may be the user using the fingers of the right or left hand (eg, index finger, thumb, etc.), or may be on the touch display through an input object detectable by the touch display (eg, a stylus, a touch display pen) The action of selecting one position, multiple positions, and/or multiple consecutive positions may include operation actions such as contact, release of touch, tap of touch, long touch, and rotation and expansion. Here, the long touch corresponds to a gesture input of moving a finger, thumb, stylus, etc. along a predetermined direction or a variable direction while the finger, thumb, stylus, etc. are in constant contact with the touch display screen, for example, like touch dragging gestures such as moving, flicking, swiping, swiping, swiping, etc. It can be seen that the gesture input is realized by the contact between the input object and the touch display screen, and the contact with the touch display screen may include direct contact with the touch screen display of a finger, thumb, or stylus, or non-direct contact with the touch screen display, and The gesture input approaching the touch screen without direct contact refers to a gesture operation action at a spatial position close to the touch screen.

A soft keyboard may include a certain number of icons (or soft keys). This may allow the user to select one or more icons in the soft keyboard and thus select one or more corresponding symbols for input. The gesture detection module 113 can detect the gesture input of the interaction between the input object and the touch display screen. The gesture detection module 113 includes various operations related to gesture input detection, such as determining whether a contact has occurred, determining whether the gesture input is continuously input, determining whether it corresponds to a predetermined gesture, determining the operation position corresponding to the gesture input, determining whether the gesture input corresponds to a predetermined gesture. Whether the operation position corresponding to the gesture input is moved to the edge position of the corresponding display area, determining whether the gesture input has been interrupted (for example, whether the contact has stopped), determining the movement of the gesture input and tracking the movement trajectory of the gesture input, etc. program module. Determining the motion of the gesture input may include determining the motion rate (magnitude), motion speed (magnitude and direction), and/or motion acceleration (change of magnitude and/or direction), motion trajectory, etc. of the operation position corresponding to the gesture input. These operations can be applied to a single manipulation location (eg, gesture input by one finger), or multiple simultaneous manipulation locations (eg, "multi-touch", ie, gesture input by multiple fingers). In some embodiments, gesture detection module 113 is used to detect motion of one or more input objects on the surface of the touch display screen or at a spatial location close to the touch display screen. The gesture detection module 113 is stored in the memory, and is called by one or more processors to realize the above gesture input monitoring, and obtain the user's operation input instruction.

In some of the embodiments of the present invention, the signal processing module 216 and the image processing module 226 in FIG. 2 may be integrated on a mainboard 206, or one or more of the modules (including the above numbers herein) may be integrated on a mainboard 206.

The gesture detection module 213 in this embodiment has the same function as the gesture detection module 113 in the embodiment shown in FIG. 1, and is not repeated here. Tired. The second touch display screen 230 and the first touch display screen 130 have the same implementation functions, but the specific product parameters may be different. The “first” and “second” are only used to distinguish different applications when expressing the embodiment. The entities in the scene can also be equally understood as the touch display screen in the traditional sense when referring to the method steps or describing a single application scene below, so it may also be referred to as the touch display screen for short elsewhere in this document. The second communication module 214 receives the ultrasound image data transmitted from the first communication module 215, and/or sends a control signal to the first communication module 215, for example, a control signal containing ultrasound imaging parameter setting information.

Based on the schematic structural diagram of the ultrasonic medical detection device (100, 200) provided in FIG. 1 or FIG. 2, the following will describe in detail how to set ultrasonic imaging parameters in conjunction with the hardware environment provided in FIG. 1 or FIG. 2.

The device disclosed in this embodiment is an ultrasonic imaging system that can adjust the imaging parameters of the ultrasonic medical inspection device through touch control. Interactive acquisition of image data and ultrasound imaging parameters increases the convenience for users to operate ultrasound equipment and improves user experience. When the parameters are adjusted by sliding on the touch screen (ie, the touch screen), the adjustment interface of these parameters is simultaneously displayed on the touch screen, and the displayed adjustment interface changes with the sliding of a finger or a stylus. When the parameters to be adjusted are such discontinuous parameters, these parameters can only take discontinuous values, so the adjustment interface displayed during adjustment will appear "jumping", which affects the user's adjustment and use experience of the parameters. Moreover, it is difficult for the user to precisely locate the adjustment mark to the desired level or the position of the gear position on the parameter adjustment interface when adjusting, which is inconvenient for the user to adjust the parameters and inconvenient to use. The ultrasonic parameter selection method provided in this embodiment can well avoid the occurrence of this problem. When the user adjusts the parameters on the touch screen, he can better experience the adjustment effect of the adjustment mark moving with the user's touch. There is no problem of inaccurate adjustment and positioning caused by random jumping of the logo, which can facilitate the user to accurately locate the desired level or gear position. Therefore, the present embodiment provides a method for controlling ultrasound imaging parameters as shown in FIG. 3 below.

For example, in the embodiment of FIG. 1 , the ultrasonic image is obtained according to the ultrasonic echo signal by the image processing module ( 126 ). The implementation of FIG. 2 In this example, an image processing module (226) is used to obtain an ultrasound image according to the ultrasound echo signal.

The preset order of arrangement in this embodiment may be an arrangement along a straight line, an arrangement along a curve, an arrangement along a circle, and the like. In one embodiment, as shown in FIG. 4 , the plurality of information indicators 305 corresponding to the plurality of discrete alternative items of the TGC are displayed in a linear arrangement on the graphical user interface of the touch display screen.

For example, the GUI includes at least two interface layers, the ultrasonic image is displayed on the first interface layer of the touch screen, and the transparent setting is superimposed on the first interface layer. the second interface layer, and a plurality of information indicators 305 are arranged on the second interface layer. Such an arrangement allows the information indicator 305 to be suspended on the ultrasound image without blocking the display of the ultrasound image, and enables the user to observe the changes of the ultrasound image due to the adjustment based on the ultrasound imaging parameters. Further, in one of the embodiments, a floating window is displayed on the touch display screen, and the floating window can be moved to any position of a pixel area on the graphical user interface. The above-mentioned area 301 is set in the floating window, and multiple information indicators 305 are set in the area 301, so that the user can visually understand multiple discrete options of relevant ultrasound imaging parameters. Based on the received adjustment trigger signal from the user, the above floating window is displayed on the touch screen.

The way of recording the corresponding relationship between the display area (309 or 418) and the discrete alternative items may be to record the pixel area range of the display area (309 or 418) on the touch screen, and the corresponding relationship between the values of the discrete alternative items is convenient for subsequent Quick lookup based on user input.

In step S224 in FIG. 3 , the first processor 140 or the second processor 240 in FIG. 2 invokes the gesture detection module (113, 213) to monitor whether the input object is on the touch screen (eg, the first touch screen 130 or the first touch screen 130 or the first touch screen). Two touches on the display screen 230).

For example, the contact of the input object with the touch display screen within a predetermined area is monitored. The predetermined area here may include a manipulable moving area of the indicator, or a manipulable moving area of multiple information indicators, for example, the predetermined area may be the area 301 or the area 416; or it may be the interface area including the area 301 or the area 416 , or may be an area other than the area 301 or the area 416 .

For another example, as shown in FIG. 6 , an ultrasound image 606 is displayed on the graphical user interface 600 , a plurality of information indicators 601 are displayed at intervals in the area 612 according to a preset sequence, and an indicator 602 is displayed in the area 612 , and a plurality of information indicators 601 are displayed in the area 612 A plurality of display areas 613 are also provided inside, and each display area 631 correspondingly displays an information indicator 601 . Wherein, in step S226, the first processor 140 or the second processor 240 in FIG. 2 calls the gesture detection module (113, 213) to monitor the input object 604 in the third area 608 and the touch display screen (130, or 230) )s contact. The third area 608 is provided in an area other than the area 612 . The touch operation in the third area 608 will affect the relative positional relationship between the plurality of information indicators 601 and the indicator marks 602 in the area 612 . A touch operation includes a contact of the input object on the touch display screen and the release of the contact.

In one embodiment, after the above step S224, it further includes:

The first processor 140 or the second processor 240 in FIG. 2 can zoom in on the relevant information according to the initial contact between the input object and the touch display screen before moving the display of the indicator or the plurality of information indicators according to the above-mentioned contact. More details of the multiple information indicators facilitate the user to more precisely locate a specific discrete value to which the ultrasound imaging parameter is expected to be adjusted.

For example, as shown in FIG. 7, an ultrasound image 702 is displayed on a graphical user interface 700, a plurality of information indicators 715 are arranged on the graphical user interface 700 along circular intervals, and each display area 718 of the plurality of spaced apart display areas 718 Displays an information indicator. The first processor 140 or the second processor 240 in FIG. 2 recognizes that the contact of the input object 703 on the touch screen corresponds to the first operation position on the touch screen, and 7191 in FIG. 7 is the initial contact of the first operation position position, and then searching for at least a part of the plurality of information indicators 715 associated with the first operation position (such as the initial contact position); secondly, enlarging at least a part of the found plurality of information indicators 715, so as to The user can clearly understand more details of the discrete alternative indicated by the information indicator. Further, in one of the embodiments, as shown in FIG. 7 , the first processor 140 or the second processor 240 in FIG. 2 , based on at least a part of the plurality of information indicators 715 found, Multiple sub-level discrete alternatives are established between the two discrete alternatives corresponding to the information indicator. For example, if the initial contact position 7191 is selected between the information indicators "35" and "40", then the multiplicity between the two discrete alternatives "35" and "40" corresponding to the two information indicators will be enlarged and expanded. Discrete alternatives for each child. The plurality of information indicators 715 in the box area on the interface 700 are transformed into the display results in the dotted box 721 pointed by the indicator line 720 after the input object 703 contacts the touch display screen. Between "35" and "40" will continue to expand into multiple sub-level discrete alternatives "37", "39", in addition, the rest of the multiple information indicators 715 will also sequentially expand multiple sub-level discrete alternatives options. The information indicators of a plurality of sub-levels are arranged and displayed on the touch display screen in a preset sequence interval, and the information indicators of one sub-level are associated with the discrete alternative items of one sub-level. Therefore, the discrete alternative items denoted by the original multiple information indicators will be enlarged and displayed in the same proportion due to the contact between the input object and the touch display screen. Of course, in order to distinguish the contact inducement that produces the magnification effect from the contact inducement of the moving indicator or multiple information indicators below, it can be judged by the contact time. If the contact time between the input object and the touch screen at the same operation position exceeds a certain amount threshold, then it is considered that at least a part of the multiple information indicators is expected to be enlarged year-on-year, and the magnification effect shown in Figure 7 will be induced. On the contrary, if the contact time between the input object and the touch screen at the same operation position does not exceed a certain threshold, it will not be recognized. It is expected that year-on-year magnification of at least a portion of the plurality of information indicators will not cause the display result of the dotted box 721 shown in FIG. 7 to occur.

In step S226 in FIG. 3 , the first processor 140 or the second processor 240 in FIG. 2 may monitor the input object on the touch display screen (eg, the first touch display screen 130 or the second touch display screen 230 ) according to the input object. touch, move the display of the indication mark or the plurality of information indicators, so that the positional relationship between the indication mark and the plurality of information indicators changes.

For example, in one of the embodiments, the first processor 140 or the second processor 240 in FIG. 2 tracks and monitors the movement of the above-mentioned contact, and determines that the movement of the above-mentioned contact is associated with the second operation position on the touch display screen. Second, the operation position is changed, and the indication mark or a plurality of information indicators are moved and displayed, so that the positional relationship between the indication mark and the plurality of information indicators is changed.

The first processor 140 or the second processor 240 in FIG. 2 determines the above-mentioned operation position on the touch display screen associated with the contact with the touch screen screen (130, or 230), that is, the second operation position. The second operation position may be located in the area 301, 416, or 612, or may be located in the area 608 (ie, an interface area 608 other than the area 612 set on the GUI in FIG. 6). In one embodiment, in the example shown in FIG. 6, the input object 604 is not slid directly in the area 612, but is slid in a control area (ie, the third area 608) on the touch screen (130, or 230). When the input object 604 slides in the control area 608, the corresponding indication mark 602 slides in the area 612 correspondingly, that is, the movement of the input object 604 in the control area 608 controls the indication mark 602 to slide in the area 612, so as to realize Adjustment of ultrasound imaging parameters. Therefore, according to the contact of the input object 604 in the third area 608, the second operation position 615 corresponding to the area 612 can be obtained.

In other embodiments, in the embodiment shown in FIG. 4 , when the input object 308 is in sliding contact in the area 301, the operation position corresponding to the area 301 can be obtained according to the sliding contact, thereby obtaining the second operation position (3111 , 3112).

Further, as shown in FIG. 4 and FIG. 5 , in step S226, the first processor or the second processor 240 in FIG. 2 calls the gesture detection module (113, 213) to track and monitor the input object and the touch display screen. (130, or 230) the contact movement, the contact movement produces a continuous contact result of the input object with the touch display screen, such as the long contact mentioned above. For example, in one of the embodiments, the continuous contact of the input object on the touch display screen (130, or 230) is monitored in the above step S226, and the first processor 140 or the second processor 240 in FIG. The gesture detection module can identify some series of continuously changing positions on the touch screen (130, or 230). Therefore, in step S228, in the embodiment shown in FIG. 4, FIG. 5 or FIG. 6, the first processor or the second processor 240 in FIG. 2 determines that the above-mentioned contact is on the touch screen (130, or 230). Multiple operating positions on the device can obtain a plurality of continuously changing second operating positions. Of course, in a plurality of continuously changing second operation positions, the arrangement and change may be along the arrangement direction of the information indicators.

Next, the first processor 140 or the second processor 240 in FIG. 2 moves and displays the indication mark or the plurality of information indicators according to the change of the second operation position, so as to make the position between the indication mark and the plurality of information indicators Relationships change. For example, in the process of moving the display indicator or a plurality of information indicators, as shown in FIG. 4 , when the contact between the input object 308 and the touch display screen moves from the first operation position 3111 to the first operation position 3112, the indicator will be displayed. The display of the logo 302 moves from the first operation position 3111 to the first operation position 3112; as shown in FIG. 5 , when the contact between the input object 403 and the touch display screen moves from the first operation position 4121 to the first operation position 4122, the The display of the indication mark 412 is moved from the first operation position 4121 to the first operation position 4122, so that the indication mark 412 is deflected and indicated between the information indicators "60" and "80"; as shown in FIG. 6, when the input object 604 and the When the touch of the touch screen moves from the first operating position 615 to the first operating position 616, the display of the indicator 602 is moved from the first operating position 615 to the first operating position 616, so that the indicator 602 deviates from one of the information indicators 601. For another example, as shown in FIG. 8 , when the contact between the input object 703 and the touch display screen moves from the first operation position 7191 to the first operation position 7192 , the display of the plurality of information indicators 715 is moved from the first operation position 7191 to the first operation position 7192 . The first operation position 7192, that is, the display result shown in the dotted box 732 pointed to by the indicator line 730 in FIG. 8, the plurality of information indicators 715 are arranged in a circle. The displayed result within the dashed box 732 is deflected clockwise by an angle such that the indicator 712 is deflected from facing the information indicator "20" to indicating between the information indicators "75" and "80".

In the above-mentioned process of displaying the indication mark or a plurality of information indicators according to the above-mentioned contact movement, the method of updating the display is adopted, that is, updating refers to deleting the display of the indication mark in the original position, and changing its position to be related to the second operation position. position, so that the indicator or a plurality of information indicators changes following the change of the second operation position. The meaning of "change" herein can also be understood as changing, transforming, or replacing the display position of the interface object on the interface.

For example, in one of the embodiments, the above steps S224 to S226 include: the first processor 140 or the second processor 240 in FIG. 2 invokes the gesture detection module to monitor the input object on the touch display screen (130, or 230) , determine a plurality of operation positions corresponding to the above-mentioned continuous contact on the touch screen, and obtain a plurality of continuously changing first operation positions; The indication mark is made to change following the change of the second operation position. As shown in FIG. 4 , when the input object 308 continues to move within a predetermined area of the touch screen along the direction 306 or 307, a continuous contact with the touch screen is generated, and the first processor monitors the continuous contact by invoking the gesture detection module , a set of multiple continuously changing second operating positions (3111, 3112) can be obtained, and this set of multiple continuously changing second operating positions (3111, 3112) sequentially changes along the arrangement direction of the information indicators, and may The arrangement direction of the information indicators spans at least one display area 309, and according to the identification of the plurality of continuously changing second operation positions (3111, 3112), the display of the indicator 302 is sequentially moved to the plurality of continuously changing second operation positions , so that the indication mark changes with the change of the second operation position.

Further, in one of the embodiments, sequentially updating the display of the indicator at the second operation position includes: the first processor or the second processor 240 in FIG. 2 invokes the gesture detection module to identify that the second operation position is in the information The position change of the arrangement direction of the indicator, according to the position change of the second operation position in the arrangement direction of the information indicator, the position of the indication mark in the arrangement direction of the information indicator is sequentially changed to the second operation position in the information indication The position in the arrangement direction of the symbols can be moved and displayed according to the change of the second operation position.

For example, assuming that (X, Y) is used to represent the coordinates of a certain pixel point in the Cartesian coordinate system, then the plurality of information indicators 305 in FIG. 4 are arranged in the vertical direction (ie, the Y direction). When FIG. 3 When the second operating position changes from position 3111 to position 3112 in the direction 307, position 3111 and position 3112 can be represented as (x1, y1), (x2, y2), respectively, where it is recognized that the second operating position is along the vertical direction (ie, Y direction) position change (y1→y2), and then according to the identified position change (y1→y2), update the position of the indicator (302) in the vertical direction (ie, the Y direction) to the position of the second operation position in the vertical direction The change position y2, that is, the position of the indicator in the Cartesian coordinate system, is at (x1, y2). Of course, the change of the second operation position may only be a change along the Y direction, that is, the position 3111 and the position 3112 may be represented as (x1, y1), (x1, y2), respectively. In this embodiment, x\y may not only represent a coordinate position value, but may also be a certain coordinate range, or may also be the coordinate position of the center point in a certain range. Similarly, in FIG. 5 , the positional change of the second operation position in the horizontal direction (ie, the X direction) is recognized, and the operation of updating the display of the indicator 412 at the second operation position 4121 is performed. This display mode can restrict the movement of the indicator, so that it can only move in the second area with the movement of the input object, for example, move to any operation position in the predetermined area along the arrangement direction of the information indicator.

In addition, in some of the embodiments, before the above-mentioned processes from steps S226 to S234 may further include:

The above-mentioned first processor 140 or the second processor 240 in FIG. 2 calls the gesture detection module to detect whether the contact between the input object and the touch display screen (130, or 230) is located in the operation position where the indication mark is located. When the touch of the display screen (130, or 230) is within the display area where the indication mark is located, the above-mentioned processes from step S226 to step S234 are performed. Conversely, when the contact between the input object and the touch screen (130, or 230) is not within the display area where the indication mark is located, the display position of the indication mark is not updated, and the above steps S226 to S234 are not performed. For the description of the process from step S226 to step S234, please refer to the above related description. This embodiment can ensure the accuracy of the control signal input and the reliability of the selection of discrete alternatives by tracking and monitoring the contact between the input object and the touch screen (130, or 230) for the input operation of the indicator. For example, as shown in FIG. 5 , first, the above-mentioned first processor or the second processor 240 in FIG. 2 calls the gesture detection module to detect whether the input object 403 is in contact with the touch display screen ( 130 , or 230 ) in the area 416 . It is located in the operation position where the indication mark 412 is located, that is, it is judged whether the contact between the input object 403 and the touch display screen (130, or 230) on the touch screen screen (130, or 230) is at the operation position 411 and the position where the indication mark 412 is located. The operating positions are coincident, if so, execute the process from step S226 to step S230, and start tracking and monitoring the movement of the input object 403 and the touch screen (130, or 230) along the direction 404 or direction 405. On the contrary, the display position of the indication mark is not updated according to the detected contact between the input object 403 and the touch screen (130, or 230), that is, the above-mentioned processes from steps S226 to S234 are not performed.

In the process from the above-mentioned steps S226 to S234, the indicator can change the display position with the continuous contact between the input object and the touch screen. In order to improve the visualization effect of the indicator with the continuous contact, the display of the indicator is updated to the second operation. In the process of positioning, the moving speed of the indicator between two operating positions on the graphical user interface can be calculated according to the visually displayed moving speed, and based on the moving speed, the movement of the indicator between the two first operating positions can be adjusted. The display moves, thereby presenting a continuous display movement effect.

In addition, in one of the embodiments, what is manipulated may not be an indicator, but a plurality of information indicators, so as shown in FIG. 8 , the above-mentioned first processor 140 or the second processor 240 in FIG. 2 invokes the gesture The detection module identifies the change direction of the second operation position generated by the above-mentioned input object 703 touching the touch screen; and moves a plurality of information indicators along the change direction according to the detected change direction. For example, in FIG. 8 , it is detected that the second operation position is changed from 7191 to 7192, and the change direction is clockwise. Therefore, moving the plurality of information indicators 715 clockwise makes the relative position between the indicator 712 and the plurality of information indicators. Relationships change.

In step S228 in FIG. 3 , the first processor 140 in FIG. 1 or the second processor 240 in FIG. 2 invokes the gesture detection module to detect the release of the contact between the input object and the touch display screen ( 130 , or 230 ).

In one of the embodiments, the first processor 140 in FIG. 1 or the second processor in FIG. 2 implements detection of the release of the above-mentioned contact in at least one of the following manners.

1. On the touch screen monitor the detachment of the contact between the input object and the touch screen (130, or 230), that is, the input object no longer performs input operations on the touch screen.

2. Monitor whether the contact between the input object 403 and the touch screen (130, or 230) is outside the predetermined area. When the above-mentioned contact is outside the predetermined area, it is considered that the above-mentioned contact has been released, and the input object is no longer displayed on the touch screen. screen for input.

When it is detected that the input object is released in contact with the touch display screen (130, or 230), the first processor 140 in FIG. 1 or the second processor in FIG. 2 will detect the release of the above-mentioned contact on the touch display screen the third operating position. For example, the contact separation between the input object and the touch display screen (130, or 230) is monitored on the touch display screen, and the operation position at which the above-mentioned contact is located before the separation is taken as the third operation position. As shown in FIG. 5 , in the area 416, the contact between the input object 403 and the touch display screen (130, or 230), the processor detects that the contact between the two moves from the first operation position 4121 to the first operation position 4122, so it also The display of the indicator 412 is continuously updated to continuously move to the first operating position 4122 . At this time, the detachment of the contact between the input object 403 and the touch screen (130, or 230) is detected at the first operation position 4122, and the operation position 4122 at which the contact was located before the detachment is identified as the third operation position. Also monitoring the continuous contact between the input object 703 and the touch display screen (130, or 230) along the direction 704 or the direction 705 within a predetermined area (in FIG. 8, the area range where a plurality of information indicators are displayed) as shown in FIG. 8, The processor detects that the contact relationship between the two moves from the first operation position 7191 to the second operation position 7192 within the predetermined area, so the display of the indicator 712 is continuously updated to continuously move to the second operation position 7192 . At this time, when the indication mark 712 is displayed at the second operation position 7192, the processor detects that the contact between the input object 403 and the touch display screen (130, or 230) is detached, and identifies the location where the above-mentioned contact was located before the detachment. The operation position 7192 is used as the third operation position. At this time, the relative positional relationship between the plurality of information indicators and the indicator marks will jump from the display result indicated by the dotted frame 732 to the display frame 733 as indicated by the indication line 740 . the indicated display result. In addition, although "first" or "second" and "third" are used in this paper to distinguish the operation positions in different situations, for the purpose of distinguishing during description, therefore, the operation positions include the first operation position and the second operation position and the third operation position; the second operation position may include the first operation position, and the first operation position is the operation position generated by the initial contact between the input object 403 and the touch display screen (130, or 230), which belongs to the second operation The starting point of the position change.

For another example, it is detected whether the contact between the input object and the touch display screen (130, or 230) is outside a predetermined area, and when the above-mentioned contact is outside the predetermined area, it is recognized that the above-mentioned contact is corresponding to the area where multiple information indicators are displayed The last operating position within the range is used as the third operating position. The predetermined area may be the above-mentioned area 416 or 301, or the above-mentioned third area (608 in FIG. 6). For example, the gray arrow marks in FIG. 6 indicate the historical display position of the mark 602 , and the black arrow marks indicate the current display position of the mark 602 . In the third area 608, the continuous contact between the input object 604 and the touch display screen (130, or 230) along the direction 603 or the direction 605 is monitored, and the processor detects that the contact between the two is in the area 612 from the first operating position. 615 moves to the first operating position 616 , so the display of the indicator 602 is also continuously updated to continuously move to the first operating position 616 . At this time, when the indication mark 602 is displayed in the first operation position 616, the processor detects that the contact between the input object 403 and the touch display screen (130, or 230) is outside the third area 608, and recognizes that the above-mentioned contact is to be The last operating position 616 corresponding to the area 612 is used as the third operating position.

In step S230 in FIG. 3 , the first processor or the second processor 240 in FIG. 2 adjusts the indication mark and the plurality of information indicators according to the relative positional relationship between the indication mark and the plurality of information indicators when the contact is released. The relative positions between the information indicators are such that the indicator is facing one of the plurality of information indicators.

For example, in one of the embodiments, the above step 230 is implemented in the following manner: the first processor or the second processor 240 in FIG. 2 sets a plurality of display areas arranged at intervals on the touch display screen, and each display area uses To display an information indicator, identify the release of the input object in contact with the touch screen to generate a third operation position on the touch screen; search for the display area associated with the above-mentioned third operation position; and, display the indicator in the search to the display area, so as to realize that the indicator mark is facing one of the information indicators among the plurality of information indicators. As shown in FIG. 5 , a plurality of display areas 418 arranged at intervals are set on the touch display screen, and each display area 418 is used to display an information indicator 415, and the release of the identification input object 403 in contact with the touch display screen is generated in the touch display. the third operation position 4122 on the screen; search for the display area 4181 associated with the above-mentioned third operation position 4122; and display the indicator 412 in the searched display area 4181. Therefore, it can be seen that when the contact between the input object 403 and the touch display screen is released, from the position indicated by the indication mark 412 between the information indicator "60" and the information indicator "80" when the above-mentioned contact is released, it jumps to The indicator 412 is opposite the location of the indicator "80" of the indicator information. Also as shown in FIG. 6 , a plurality of display areas 613 arranged at intervals are set on the touch display screen, each display area 613 is used to display an information indicator 601, and the release of the contact between the input object 604 and the touch display screen is generated when the touch screen is touched. the third operation position 616 on the display screen; search for the display area 6131 associated with the above-mentioned third operation position 616; and display the indication mark 602 in the searched display area 6131. Therefore, it can be seen that when the contact between the input object 604 and the touch display screen is released, from when the above-mentioned contact is released, the indication mark 602 indicates a position deviating from one of the plurality of information indicators, and jumps to a position indicating that the indication mark 602 is facing The position of one of the information indicators (indication mark 602 is opposite indicator scale "12").

In the above-mentioned step 230, the first processor or the second processor in FIG. 2 uses one of the following manners to search for the display area associated with the above-mentioned third operation position.

1. For example, as shown in FIG. 5, find the display area 4181 closest to the third operation position 4122, and use the display area closest to the third operation position as the display area associated with the third operation position.

2. For example, as shown in FIG. 6 , the contact between the input object 604 and the third area 608 causes the display area 6131 to be crossed last by the display of the indication mark. That is to say, according to the third operation position, find the display area that the continuous contact between the input object 604 and the touch display screen lasts in the area 612 .

For another example, in one of the embodiments, the above step 230 is implemented in the following manner: the first processor or the second processor 240 in FIG. 2 sets a plurality of display areas arranged at intervals on the touch display screen, each display area for displaying an information indicator; identifying a third operating position on the touch display screen generated by the release of the input object in contact with the touch display screen; searching for one of a plurality of information indicators located near the indication mark; and, finding the One of the multiple information indicators is displayed directly opposite the indicator. For example, as shown in the dotted box 733 in FIG. 8 , a plurality of display areas 718 arranged at intervals are set on the touch display screen, and each display area 718 is used to display an information indicator 715; it is recognized that the input object 703 is in contact with the touch display screen The release of the resulting third operating position 7192 on the touch display screen; look for one of a plurality of information indicators located near the indicator 712, such as the information indicator "80", or the information indicator "75"; and, place the The information indicator "80" or the information indicator "75" is displayed directly opposite the indicator 712, in a dashed box in FIG. 8 . Therefore, it can be seen that when the contact between the input object 703 and the touch screen is released, from the position indicated by the indicator 712 in the middle of the information indicators "75" and "80" when the above-mentioned contact is released, the indicator 712 jumps to the positive position. To indicate the information indicator "80".

In step S232 in FIG. 3 , the first processor or the second processor in FIG. 2 determines discrete alternatives corresponding to the above-mentioned information indicators that indicate that the marks are facing.

In the embodiment of FIG. 5 , the above-mentioned indication mark is the information indicator “80” facing directly, and the discrete alternative is determined to be the scale “80”; in the embodiment of FIG. The discrete alternative is scale "12". Wherein, each processor can determine the discrete alternative item associated with the information indicator whose indication mark is facing by looking up the relationship between the display area occupied by the information indicator and the discrete alternative item.

Then, in step S234 in FIG. 3 , the first processor or the second processor in FIG. 2 adjusts the corresponding ultrasonic imaging parameters according to the determined discrete alternatives corresponding to the information indicator that indicates that the indicator is facing parameter values, and use the adjusted parameter values to obtain the aforementioned ultrasound images. Based on the determined discrete alternatives, the ultrasound imaging parameters used in the ultrasound scan are reset by the processor.

In addition, for example, in the embodiment shown in FIG. 2 , the second processor obtains the parameter value corresponding to the ultrasound imaging parameter according to the determined discrete alternative item associated with the information indicator that the indication mark is facing, and then the intelligent controller obtains the parameter value corresponding to the ultrasonic imaging parameter. 270 generates a control signal containing the parameter value, and outputs the control signal to the first communication module 215 through the second communication module 214, so as to control the ultrasonic scanning of the target tissue by the probe and the formation of the ultrasonic image through the first processor , thereby updating the display result of the ultrasound image.
