Processing device 120 may be used to process information and/or data, for example, processing device 120 may be used to process information and/or data related to coil display. In some embodiments, a processing device may acquire a coil position of a scan imaging coil for scanning a target object and detect user operation of an operation control to determine whether the coil position is displayed in a scan image. In some embodiments, processing device 120 may process data, information, and/or processing results obtained from other devices or system components and execute program instructions based on such data, information, and/or processing results to perform one or more functions described herein. For example, the processing device 120 may receive a user operation of an operation control from the terminal device 130, display a coil position in a scan configuration interface of the imaging device 110, and the like. In some embodiments, the processing device 120 may be a single server or a group of servers. The server group may be centralized or distributed.

For example, processing device 120 may access information and/or data from imaging device 110, terminal device 130, and/or storage device 140 via network 150. In some embodiments, the processing device 120 may be implemented on a cloud platform.

The terminal device 130 may include a mobile device 130-1, a tablet computer 130-2, a notebook computer 130-3, etc., or any combination thereof. In some embodiments, the terminal device 130 may interact with other components in the coil display system over a network. For example, the terminal device 130 may send one or more control instructions to the imaging device 110 to control the imaging device 110 to scan the target object in accordance with the instructions. For another example, the terminal device 130 may also receive and display a medical image obtained by imaging the imaging signal by the processing device 120. In some embodiments, the terminal device 130 may be part of the imaging device 110. In some embodiments, the terminal device 130 may be integrated with the processing device 120 as an operator console for the imaging device 110.

As another example, the scene 100 may implement similar or different functionality on other devices. However, such changes and modifications do not depart from the scope of the present application.

Fig. 2 is an exemplary flow chart of an exemplary coil display method according to some embodiments of the present description. In some embodiments, the process 200 may be performed by a processing device (e.g., the processing device 120). For example, the flow 200 may be stored in a storage device (e.g., a processing device's own memory unit or external storage device) in the form of a program or instructions that, when executed, may implement the flow 200. As shown in fig. 2, the process 200 may include the following steps.

At step 210, coil positions of an imaging coil for scanning a target object are acquired. In some embodiments, step 210 may be performed by coil position acquisition module 510.

The target object may include a patient or other medical subject (e.g., a test mouse or other animal), and the like. The target object may also be part of a patient or other medical subject, including organs and/or tissues, e.g., heart, lung, ribs, abdominal cavity, etc.

Imaging coils are an important component of the functioning of imaging devices. Taking a magnetic resonance imaging apparatus as an example, the magnetic resonance imaging apparatus mainly includes a magnet, an imaging coil, a receiving link, and the like. The imaging coils may include gradient coils, radio frequency coils, receive coils, and the like, among others. A uniform static magnetic field is generated by a superconducting magnet, hydrogen nuclear spin precession is excited by a radio frequency transmitting coil to generate a magnetic resonance signal, and the signal is subjected to spatial information coding by a gradient coil. The magnetic resonance signals are acquired by a radio frequency receiving coil and are converted into digital signals through a receiving link, and finally, a computer is used for reconstruction to obtain a magnetic resonance image. The coil is an important component of the magnetic resonance system and has a decisive effect on the image quality of the magnetic resonance system. In some embodiments, the imaging coils may include one or more of gradient coils, video coils, receive coils, and the like.

The coil position may refer to the relative position of the imaging coil to a reference. For example, the position of the imaging coil compared to the scan couch, the position of the imaging coil compared to a target object located on the scan couch, or the position of the imaging coil compared to other objects, etc.

In some embodiments, the coil position may be represented in position coordinates. For example, the coil position may be determined based on spatial coordinates of the geometric center of the imaging device. For example, a spatial coordinate system may be established based on the geometric center of the imaging device, the coordinates of the geometric center may be set to (0, 0), and when the imaging coil of the imaging device moves, the spatial coordinates of the imaging coil (the spatial coordinates may be determined with its geometric center, for example, the centroid coil center, etc.) may be within the spatial coordinate system set with the geometric center of the imaging device as the origin, for example, the spatial coordinates of the imaging coil may be (30,50,60).

In some embodiments, the imaging coil used to scan the target object may be one or more of a plurality of coils of an imaging device, e.g., one or more radio frequency coils, a receive coil, etc. In some embodiments, the imaging coil may be a segment or segments in a certain coil of the imaging device selected by the user.

In some embodiments, the user may adjust the position of the imaging coil to place the imaging coil in a different position for more accurate scanning.

In some embodiments, the coil position may be determined based on a control system of the imaging device, e.g., the control system may record the position coordinates of each movement of the coil.

Step 220, detecting a user operation of an operation control to determine whether the coil position is displayed in the scanned image. In some embodiments, step 220 may be performed by coil position display module 520.

The user may be an operator of the imaging device. Such as doctors, researchers, etc. The operation control may be a button of an operation interface of the imaging device, a checkbox, an input box, a draggable scan point, or the like. In some embodiments, the user may effect operation of the operational control in a variety of ways, such as touch, voice, gesture, external device (mouse, keyboard, etc.) operation, and so forth.

The scan image may refer to an image generated from signals acquired by the imaging coil after scanning the target object based on the imaging device. For example, an image obtained by image reconstruction is performed based on the imaging signal.

In some embodiments, the processing device may detect a user operation of the operation control based on whether a corresponding operation instruction is received. For example, the operation space of whether to display the coil position in the scan image may be similar to the "yes/no to display the coil position in the scan image" operation space, and the user selection of "yes" may trigger an instruction to display the coil position in the scan image, and the user selection of "no" may trigger an instruction to not display the coil position in the scan image. In some embodiments, the user may implement the operation of the operation control by selecting, switching, dragging, voice input, and the like.

In response to a user operation of the operation control, the processing device may display a position of the imaging coil relative to the target object at the time of scanning in the scanned image when the coil position needs to be displayed in the scanned image. In some embodiments, displaying the coil position may indicate the coil position by various means, such as solid lines, dashed lines, boxes, arrows, and the like. In some embodiments, the boundary of the display coil in the scan image may be taken as the coil position. The boundary of the coil is displayed in a manner that avoids obscuring the tissue structure of the target object in the scanned image.

In some embodiments, the scanned image may be a two-dimensional image or a three-dimensional image, which is not limited in this specification.

In some embodiments, the coil display method may further include step 230 of detecting user operation of the operation control to determine whether to display the coil position in the pre-scan configuration interface. In some embodiments, step 230 may be performed by coil position display module 520.

The pre-scan configuration interface may be a configuration interface of a scan protocol prior to scanning the target object. In some embodiments, the scan protocol may include a plurality of parameters, e.g., scan parameters, reconstruction parameters, etc. In some embodiments, the scanning protocol may include scanning time, signal-to-noise ratio, number of excitations, spatial resolution, repetition time, readout signal pattern, etc., or any combination thereof. In some embodiments, the scanning protocol may be stored in a storage device and/or an external data source.

In some embodiments, the processing device may determine whether to display the coil position in the pre-scan configuration interface based on a user operation. For example, in response to a user clicking a dialog box for "displaying a coil position in a configuration interface before scanning", pressing a button for "displaying a coil position in a configuration interface before scanning", making a relevant voice for "displaying a coil position in a configuration interface before scanning", performing a gesture action for "displaying a coil position in a configuration interface before scanning", and the like, the processing apparatus performs a corresponding operation.

In some embodiments, when the user sets by operating the control that the coil position is not displayed in the configuration interface, the coil position may not be indicated on the model structure of the target object displayed in the configuration interface. For example, referring to fig. 6A and 6B, fig. 6A is an exemplary schematic diagram showing no coil positions in a configuration page according to some embodiments of the present specification, and fig. 6B is an exemplary schematic diagram showing coil positions in a configuration page according to some embodiments of the present specification. Wherein the dashed box in fig. 6B represents the coil position of the scan coil.

In some embodiments of the present disclosure, whether to display the coil position in the configuration interface and/or the scanned image before scanning is implemented based on the user requirement, which can reduce the experience requirement on the operator, improve the scanning accuracy, improve the scanning image quality, increase the coil visualization feature, enrich the use rights of the user, implement the coil virtualization, and help the technician or the developer to analyze the image quality more intuitively and conveniently.

FIG. 3 is an exemplary flow chart of an exemplary determination of whether a coil position matches a scan location according to some embodiments of the present description. In some embodiments, the process 300 may be performed by a processing device. For example, the flow 300 may be stored in a storage device (e.g., a self-contained memory unit of a processing device or an external memory device) in the form of a program or instructions that, when executed, may implement the flow 300. As shown in fig. 3, the process 300 may include the steps of:

step 310, it is determined whether the coil position matches the position of the scan site of the target object.

The scan site may include organs and/or tissues of the target object, e.g., heart, lung, ribs, abdominal cavity, etc.

Matching may refer to the current coil's position being able to cover the scan site of the target object. For example, an overlay can be considered a match, and an overlay can not be considered a mismatch. For example, when the coil completely covers the heart region of the target object when the heart of the target object is scanned, it may be determined that the coil position matches the position of the scanning site.

In some embodiments, the processing device may determine whether the coil position matches the position of the scan site in a variety of ways. For example, the processing apparatus may acquire information of the target object on the scanning bed, such as height, lying position, and the like, by means of laser radar scanning, infrared ranging, and the like, estimate the position coordinates of the scanning site in a spatial coordinate system with the center of the imaging apparatus as the origin of coordinates based on the information, and determine whether the coil position matches the position of the scanning site based on the position coordinates and the position coordinates (coil position) of the imaging coil. For another example, the processing device may acquire a localization image of the target object and determine whether the coil position matches a position of the scan site based on the localization image. For more explanation of determining whether the coil position matches the position of the scan site based on the localization image, see fig. 4 and its associated description.

In some embodiments, a subsequent process, e.g., a scanning process, may be performed when the coil position is determined to match the position of the scanning location, and step 320 may be performed when the coil position is determined to not match the position of the scanning location.

In response to the coil position not matching the position of the scan site, a prompt is issued to the user, step 320.

In some embodiments, the prompt may be used to inform the user of information related to the coil position. For example, prompting may include informing a user that the coil position needs to be adjusted and/or the coil reselected. For another example, prompting may include informing the user whether the current coil position matches the position of the scan site, whether to enter a subsequent procedure, and so forth. It will be appreciated that there may be a variety of reasons for the mismatch of the coil position and the position of the scan site, for example, the operator may not select the coil segment properly (e.g., the selected coil is too small or the selected coil position has a limited range of movement to cover the scan site), the position of the coil is not accurately positioned, etc., and based on the reasons for the mismatch of the positions, the processing device may send a corresponding indication to the user that the coil is reselected if the coil is improperly selected, and that the coil position is not accurately positioned. In some embodiments, the processing device may also send a prompt to the user directly to adjust the coil position and reselect the coil, with the user selecting whether to reselect the coil or adjust the coil position at his/her discretion.

In some embodiments, the types of cues may include image cues, text cues, voice cues, vibration cues, and so on.

In this embodiment, by determining whether the coil position is matched with the scanning position and sending a prompt to the user, the requirement on experience of the operator can be reduced, accurate placement of the coil is achieved, and the problems of uneven distribution of image signals, reduced signal-to-noise ratio and the like caused by deviation of the coil from the scanning position are avoided.

FIG. 4 is an exemplary flow chart for determining whether a coil position matches a scan location according to some embodiments of the present disclosure. In some embodiments, the process 400 may be performed by the processing device 120. For example, the flow 400 may be stored in a storage device (e.g., a self-contained memory unit of a processing device or an external memory device) in the form of a program or instructions that, when executed, may implement the flow 400. As shown in fig. 4, the process 400 may include the steps of:

in step 410, a positioning image of the target object is acquired.

The scout image may refer to an acquired image including the scan bed and the target object. For example, an image of a target object located on a scanning bed. The localization image may be used to achieve localization of the scan site in a scanning examination, i.e. to determine the corresponding position of the planned scan range on the body structure of the target object. In some embodiments, the scout image may be obtained by camera shooting, scout scanning, or the like.

Step 420, determining a position of the scanning site in the positioning image based on the positioning image.

The position of the scanning spot in the image may refer to the area of the scanning spot's position in the positioning image. In some embodiments, the location may correspond to an anatomical location of the target object to more accurately determine the scan site.

In some embodiments, the processing device may determine the location of the scan site in the positioning image by means of image recognition. For example, the processing device may invoke a trained image recognition model from which the location of the scan site in the scout image is determined.

In some embodiments, the image recognition model may be a machine learning model. Such as a deep neural network model, a convolutional neural network model, and the like. The input of the image recognition model can be a positioning image and a scanning position, the output can be a recognition frame of the scanning position in the positioning image, and the recognition frame can frame the position of the area where the scanning position is in the positioning image. In some embodiments, the initial model may be trained by sample data to obtain an image recognition model. The sample data may include a training sample, which may be a sample positioning image, and a corresponding tag, which is the position of the scan site in the sample positioning image. The label may be obtained by manual labeling or other modes, and the training mode may be various common training modes, such as gradient descent method, etc.

Step 430, determining whether the coil position matches the position of the scan site based on the position of the scan site in the scout image.

In some embodiments, the processing device may determine whether the coil position matches the position of the scan site based on the position of the scan site in the scout image and the manner in which the coil covers the scan site. For example, when the scan site is the abdomen, it is determined that the coil does not cover the scan site when the coil is located above the abdomen of the target object but does not cover the abdomen completely by the coil position, and when the scan site is the brain, it is determined that the coil does not cover the scan site when the coil is located at the brain but does not cover the brain completely due to the small coil size.

In some embodiments, the processing device may establish a mapping of the positioning image to spatial coordinates established based on a center of the imaging device, and determine spatial coordinates corresponding to the scan location in the current positioning image. And determining whether the coil position matches the position of the scan site based further on the position coordinates corresponding to the scan site and the position coordinates of the imaging coil.

In the embodiment, by acquiring the positioning image and judging whether the coil position is matched with the scanning part in an image recognition mode, an operator can be prevented from judging according to experience, the influence of artificial subjective factors is reduced, and the accuracy of the coil placement position is improved.

It should be noted that the above descriptions of the respective flows are merely for illustration and description, and do not limit the application scope of the present specification. Various modifications and changes to the flow may be made by those skilled in the art under the guidance of this specification. However, such modifications and variations are still within the scope of the present description. For example, a preprocessing step, a storage step, etc. may be included in each flow.

Fig. 5 is an exemplary block diagram of an exemplary coil display system according to some embodiments of the present description. As shown in fig. 5, the coil display system 500 may include a coil position acquisition module 510 and a coil position display module 520.

The coil position acquisition module 510 may be used to acquire coil positions of an imaging coil for scanning a target object.

The coil position display module 520 may be used to detect user operation of the operation control to determine whether to display the coil position in the scanned image.

The coil position display module 520 may also be used to detect user manipulation of the operational controls to determine whether to display the coil position in the pre-scan configuration interface.

In some embodiments, the coil display system 500 may further include a determination prompt module 530 for determining whether the coil position matches a position of a scan site of the target object, and in response to the coil position not matching the position of the scan site, issuing a prompt to the user.

It should be noted that the above description of the coil display system 500 and its modules is for convenience of description only and is not intended to limit the present description to the scope of the illustrated embodiments. It will be appreciated by those skilled in the art that, given the principles of the system, various modules may be combined arbitrarily or a subsystem may be constructed in connection with other modules without departing from such principles. In some embodiments, the modules may be different modules in a system, or may be one module to implement the functions of two or more modules. For example, each module may share one memory module, or each module may have a respective memory module. Such variations are within the scope of the present description.

Some embodiments of the present description also relate to a coil display device including a processor for performing the coil display method.

Some embodiments of the present description also relate to a computer-readable storage medium storing computer instructions that, when read by a computer in the storage medium, perform the coil display method.

Benefits that may be brought by the present application include, but are not limited to, (1) reduced operator experience requirements. If the operator has inaccurate knowledge of the exact position of the scan site, the coil position can be displayed to determine if the coil placement is accurate. If the coil is not placed in time, the configuration interface displays a prompt of the coil being placed in error, so that the scanning time of technicians is saved, the scanning efficiency is improved, and the scanning accuracy is improved. The accuracy of the scanning position is ensured by accurately displaying the coil position, so that the condition that rescanning is required due to inaccurate coil position is avoided, and the scanning image quality is improved. The accurate placement of the coil can avoid the problems of uneven image signal distribution, reduced signal to noise ratio and the like caused by the deviation of the coil from the scanning part, and (4) the coil visualization characteristic is added, so that the selection of operators is enriched. The operator can choose whether to display the coil position according to the habit preference, so that the coil position can be displayed on the operation interface or the imaging interface, and (5) the coil virtualization is realized, the technician or the patient is helped to know the coil position information, and the doctor or the patient is helped to analyze the image quality reasons. And (6) the method helps technicians or research personnel to analyze the image quality more intuitively and conveniently. When the condition of poor image quality occurs, the relative relation between the coil and the scanning part can be seen in the scanned image, so that whether the image quality is related to the coil placement position or not can be analyzed more conveniently. It should be noted that, the advantages that may be generated by different embodiments may be different, and in different embodiments, the advantages that may be generated may be any one or a combination of several of the above, or any other possible advantages that may be obtained.
