Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the drawings are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.

In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; the device can be mechanically connected, electrically connected and communicated; either directly, or indirectly, through intermediaries, may be in communication with each other, or may be in interaction with each other, unless explicitly defined otherwise. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances. The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

At present, before a patient part of a human body is scanned, a doctor is required to set the scanned part, namely a scanning area, and the CT machine finishes a scanning protocol from a start line to an end line of the scanning area, namely a scanning action is executed. Since doctors often pay great attention to specific parts, different scan parameters, i.e. a reconstruction region, are generally required to be set for the specific parts. When there are a plurality of such specific sites, i.e. a plurality of reconstruction regions, the creation of which involves a number of parameters and is therefore very complex, there are only two options once the doctor considers that an adjustment of the reconstruction region is required: either deleting the reconstruction region, resetting a new reconstruction region at a suitable position, or adjusting the original reconstruction region to a suitable position. However, the current reconstruction region adjustment method is very inconvenient, and is difficult to adjust to a proper position during use, and especially cannot be continuously adjusted when one reconstruction region is compressed to the minimum, so that the reconstruction process is very tedious and has low efficiency.

As shown in fig. 1, the method for reconstructing a CT scan region provided by the present invention includes the following steps:

s1, acquiring scanning area data.

In this step, the scan area data is determined by a scan area defined by a doctor, and after the scan area data is determined, the scan data is obtained by scanning in the scan area by a CT machine, the scan data is used for imaging, and the reconstruction area is used for defining an area and imaging by using the scan data in the area.

S2, generating at least two reconstruction areas according to the scanning area data.

It should be noted that, determining a scan region according to scan region data, and generating a reconstruction region in the scan region belongs to the prior art. This is because the generation of each reconstruction region is determined by the corresponding parameters, and the determination of the region and the generation of the parameters can be determined by the doctor. The generation process of each reconstruction region is independent, so that the reconstruction regions can be generated respectively.

S3, acquiring adjustment information and a size threshold value of the reconstruction region.

The adjustment information of the reconstruction region refers to information of adjustment of the reconstruction region, such as an adjustment direction and an adjustment amplitude, inputted by the doctor. One possible adjustment information is: down to a width of 5 cm. One possible size threshold is: the width value is 10 cm or more.

One possible method of obtaining the adjustment information and the size threshold is: the size threshold is set by a doctor according to the size of the display screen before CT detection, for example, the size threshold is more than or equal to 10cm; the method for acquiring the adjustment information is that a user drags the adjustment information on a display screen through a mouse, and the adjustment information is acquired by detecting the dragging direction and amplitude of the mouse.

And S4, if the size value of one of the adjacent reconstruction regions is smaller than the size threshold value, moving the reconstruction region with the width smaller than the size threshold value into the other adjacent reconstruction region in an overlapping mode.

In this step, reference may be made to the one shown in fig. 2. If the size threshold at this time is: the length value in the vertical direction is more than or equal to 10 cm. In fig. 2, the scan area 2 is an area corresponding to the scan protocol 2 (upper left isosceles trapezoid number 2), the reconstruction area 2.1 is a reconstruction area (narrow stripe area) corresponding to the reconstruction protocol 2.1 (upper left right trapezoid 2.1), and the reconstruction area 2.2 is a reconstruction area corresponding to the reconstruction protocol 2.2 (upper left right trapezoid 2.2). When the user drags the upper edge of the reconstruction area 2.1 to drag downwards, when the length value of the reconstruction area 2.1 in the vertical direction reaches 10 cm, the reconstruction area 2.1 cannot be compressed any more, if the user continues to drag the upper edge of the reconstruction area 2.1 to move downwards, the reconstruction area 2.1 enters the reconstruction area 2.2 and finally takes the state of the reconstruction area 2.1 'in fig. 2, and at the moment, the reconstruction area 2.1 coincides with the reconstruction area 2.2, and the overlapping part is 2.1'; if the user continues to drag the reconstruction region 2.1 (i.e. 2.1'), the common upper edge of the reconstruction region 2.2 moves downwards, the reconstruction region 2.1 no longer changes, and the length value of the reconstruction region 2.2 in the vertical direction is gradually compressed. In this way, an adjustment of the reconstruction region is achieved.

After the reconstruction region is adjusted, reconstructing according to the data of the reconstruction region to generate a reconstruction image, and switching to the corresponding reconstruction image when a doctor needs to observe the reconstruction region.

By adopting the technical scheme, a doctor can conveniently adjust the reconstruction areas without changing the dragging positions, and can adjust a plurality of reconstruction areas, so that the method is very convenient and has high adjustment efficiency.

s201, acquiring at least two reconstruction protocols;

In this embodiment, the reconstruction region is generated by inputting a form of reconstruction protocol. By adopting the technical scheme, compared with manual drawing of the reconstruction region, batch adjustment can be performed, and particularly, the rapid reconstruction region setting can be performed aiming at CT detection of a certain part. Specifically, a limited number of reconstruction protocols can be set for a certain part, and the reconstruction protocols can be used for reconstructing areas with fixed positions, fixed sizes and fixed numbers, so that the efficiency in reconstruction is improved.

In one possible implementation, step S5 further includes:

S6, respectively generating switching labels according to the scanning protocols, wherein the switching labels, the scanning protocols and the reconstructed images are associated.

As illustrated in fig. 2, the right trapezoid areas 2.1, 2.2 in the upper left corner are the corresponding switch labels.

And S7, displaying the switching label on a display screen.

As shown in fig. 2, the switch tabs are all disposed on the left side of the display screen.
