[0048] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The scanning field of view refers to the size of the field of view set during computed tomography (CT), which determines the area that can be fully covered during the scanning process. The reconstruction field of view refers to the size of the field of view displayed in the image reconstructed by the computer after the CT scan. Normally, the scanning field of view should be greater than or equal to the reconstruction field of view, that is, the scanning field of view area covers the reconstruction field of view area.

[0050] For obese patients, the area to be examined is relatively large. Due to the limitation of the detector's fan-shaped angle, the scanning field of view cannot completely cover the area to be examined. Therefore, the extended reconstruction field of view function is introduced. The extended reconstruction field of view is to increase the reconstruction field of view area on the basis of the scanning field of view to obtain a larger image reconstruction field of view. Although the extended reconstruction field of view can cover a larger inspection range, the image quality obtained by the extended reconstruction field of view needs to be improved.

[0051] See also Figure 1a The circular area marked with number 1 represents the scanning field of view. When the gantry is scanning and rotating, this area can be completely covered by rays. The gantry can collect data in this area at any angle. The circular area marked with number 2 represents the extended reconstruction field of view. This area can only be covered by rays when the gantry is at a specific angle. Figure 1b , Figure 1b Point A in the figure is located in the extended reconstruction field of view. When the tube is directly above, data of this point can be collected. Figure 1c , Figure 1c Point A in the figure is located in the extended reconstruction field of view. When the tube is located on the right side, the data of point A cannot be collected. Figure 1b and Figure 1c The detectors are symmetrically distributed with respect to the center line of the scanning field of view. In other examples, such as Figure 1d As shown, the detectors are asymmetrically distributed relative to the center line of the scanning field of view, and the area on one side of the center line of the scanning field of view is completely covered ( Figure 1d The area on the other side of the center line of the scanning field of view is not completely covered ( Figure 1d ), the data in the area that is not fully covered is missing, resulting in incomplete data within the extended reconstruction field of view.

[0052] Expanding the reconstruction field of view allows doctors to observe a wider area, display more tissue structures and anatomical information on the image at the same time, and thus more comprehensively evaluate lesions or abnormalities. However, since the data within the expanded reconstruction field of view is incomplete, problems such as increased noise and artifacts may occur during image reconstruction. These problems can cause image blurring, reduced resolution, and reduced contrast, affecting the accuracy of diagnosis.

[0053] In the related art, the image of the extended reconstructed field of view area and the image of the scanned field of view area are usually displayed on the same image at the same time, and there is no obvious distinction. If the image of the extended reconstructed field of view area can be highlighted, it can help doctors distinguish the two areas more clearly, and improve the accuracy and reliability of observing and analyzing images.

[0054] Based on this, an embodiment of the present specification provides a medical image display method. After determining the extended reconstruction field of view area and the scanning field of view area of ​​the target medical image that are located outside the scanning field of view, the extended reconstruction field of view area and the scanning field of view area are distinguished and displayed. The image of the scanning field of view area provides higher spatial resolution and contrast, which is suitable for detailed analysis and diagnosis of specific areas, while the image of the extended reconstruction field of view area provides a more comprehensive field of view, which helps doctors find lesions or abnormalities in a larger range. Therefore, by distinguishing and displaying the extended reconstruction field of view area and the scanning field of view area, the scanning field of view area and the extended reconstruction field of view area can be distinguished when displaying the target medical image, thereby improving the diagnostic efficiency and reducing the misdiagnosis rate.

[0055] This specification provides a method for displaying medical images. Figure 1e , the medical image display method may include the following steps:

[0056] S110 . Determine an extended reconstruction field of view and a scanning field of view of a target medical image. The extended reconstruction field of view is a reconstruction area outside the scanning field of view.

[0057] S120 , distinguishing and displaying the extended reconstruction field of view area and the scanning field of view area.

[0058] Specifically, in some cases, important tissues or lesions may be located outside the standard scanning field of view. By extending the reconstruction field of view, the risk of omission can be reduced. When performing a CT scan, first set the scanning field of view to ensure that the main examination area can be covered. If the patient is large or requires a wider coverage area, start the extended reconstruction field of view imaging function to obtain a reconstructed area outside the scanning field of view. The CT device collects complete data within the scanning field of view. In the extended reconstruction field of view area, only when the gantry is at a specific angle, partial data corresponding to the area covered by the ray at this time can be collected. Image reconstruction is performed on the collected complete data including the scanning field of view and partial data in the extended reconstruction field of view area to obtain a target medical image containing the scanning field of view area and the extended reconstruction field of view area. The extended reconstruction field of view area and the scanning field of view area can be determined in the target medical image. In order to distinguish the scanning field of view area and the extended reconstruction field of view area in the target medical image, the extended reconstruction field of view area and the scanning field of view area are distinguished and displayed.

[0059] It should be noted that when the extended reconstruction field of view imaging function is started, the display mode of the extended reconstruction field of view area and the display mode of the scanning field of view area are dynamically adjusted according to clinical needs and specific circumstances. The display mode can be configured by factory preset or manual adjustment. Differentiated display can mark the extended reconstruction field of view area and the scanning field of view area on the same image as a whole, so that the doctor can clearly identify the image of the two areas. It can also display the extended reconstruction field of view and the scanning field of view area separately, not in the same image, which will be described in detail below.

[0060] In the above implementation, after the extended reconstruction field of view area and the scanning field of view area of ​​the target medical image that are outside the scanning field of view are determined, the extended reconstruction field of view area and the scanning field of view area are distinguished and displayed. The image of the scanning field of view area provides higher spatial resolution and contrast, which is suitable for detailed analysis and diagnosis of a specific area, while the image of the extended reconstruction field of view area provides a more comprehensive field of view, which helps doctors find lesions or abnormalities in a larger range. Therefore, by distinguishing and displaying the extended reconstruction field of view area and the scanning field of view area, the scanning field of view area and the extended reconstruction field of view area can be distinguished when displaying the target medical image, thereby improving the diagnostic efficiency and reducing the misdiagnosis rate.

[0061] In some embodiments, see Figure 2 , the method may further include the following steps:

[0062] S210: Display the target medical image.

[0063] The extended reconstruction field of view area and the scanning field of view area in the target medical image are displayed in the same manner.

[0064] Specifically, when performing a CT scan, the CT device will completely collect data within the scanning field of view. For the extended reconstruction field of view area, data can only be partially collected when the gantry is at a specific angle. By reconstructing the image of the complete data collected within the scanning field of view and the partial data in the extended reconstruction field of view area, a target medical image including the extended reconstruction field of view area and the scanning field of view area is obtained. In the target medical image, the extended reconstruction field of view area and the scanning field of view area are displayed in the same way, which means that the extended reconstruction field of view area and the scanning field of view area cannot be visually distinguished. Therefore, it is necessary to identify and distinguish the extended reconstruction field of view area and the scanning field of view area in the image according to clinical needs to help doctors accurately interpret the image.

[0065] S220 : When receiving an operation to distinguish the display area, distinguish and display the extended reconstruction field of view area and the scanning field of view area in the target medical image.

[0066] The distinguishing operation may clearly identify and distinguish the extended reconstruction field of view area from the scan field of view area. The distinguishing mark may be a mark or a tag actually added to the image.

[0067] Specifically, when receiving the display area differentiation operation, a differentiation mark is added to the target medical image to ensure that the extended reconstruction field of view area and the scan field of view area are clearly indicated to differentiate the two areas. The differentiation mark can adopt different colors, border styles, etc.

[0068] In the above implementation, the target medical image is displayed, and when an operation to distinguish the display area is received, the extended reconstruction field of view area and the scanning field of view area are distinguished and displayed in the target medical image, thereby improving the diagnosis efficiency and reducing the misdiagnosis rate.

[0069] In some embodiments, displaying the extended reconstruction field of view region and the scanning field of view region separately may include: displaying a boundary mark at the boundary between the extended reconstruction field of view region and the scanning field of view region.

[0070] Specifically, after acquiring the target medical image, in order to distinguish the extended reconstruction field of view area from the scanning field of view area, an edge detection algorithm is used or the image information of the original scan is processed to determine the boundary between the extended reconstruction field of view area and the scanning field of view area in the target medical image. The boundary between the extended reconstruction field of view area and the scanning field of view area is clearly marked in the target medical image using a boundary marker. For example, the boundary between the extended reconstruction field of view area and the scanning field of view area can be clearly marked by lines, color markings, etc.

[0071] In some embodiments, a medical image corresponding to the extended reconstruction field of view, a medical image corresponding to the scanning field of view, and a target medical image are stored. By comparing and analyzing the medical image corresponding to the extended reconstruction field of view and the medical image corresponding to the scanning field of view, the boundary between the extended reconstruction field of view and the scanning field of view can be identified in the target medical image.

[0072] In the above implementation, a boundary mark is displayed at the boundary between the extended reconstruction field of view area and the scanning field of view area, so as to distinguish the scanning field of view area from the extended reconstruction field of view area, thereby improving the diagnosis efficiency and reducing the misdiagnosis rate.

[0073] In some embodiments, distinguishing and displaying the extended reconstruction field of view area and the scanning field of view area may include: displaying a first edge marker at the edge contour of the extended reconstruction field of view area in the target medical image, and displaying a second edge marker at the edge contour of the scanning field of view area in the target medical image, wherein the first edge marker is different from the second edge marker.

[0074] Specifically, in the target medical image, an edge detection algorithm or region selection technique is used to identify and determine the edge contour of the extended reconstruction field of view area and the edge contour of the scanning field of view area. Next, a first edge marker is displayed at the edge contour of the extended reconstruction field of view area in the target medical image to clearly mark the extended reconstruction field of view area. A second edge marker is displayed at the edge contour of the scanning field of view area in the target medical image to clearly mark the scanning field of view area. In order to more clearly distinguish the scanning field of view area from the extended reconstruction field of view area, the first edge marker is different from the second edge marker, for example, different colors or marker styles can be used. It should be noted that the first edge marker and the second edge marker are displayed simultaneously in the target medical image, so that the extended reconstruction field of view area and the scanning field of view area can be compared and identified at the same time, thereby more accurately understanding and analyzing the inspection image content.

[0075] In some embodiments, first, the parameters of the two circles of the extended reconstruction field of view and the scanning field of view are determined, and the parameters of each circle include the coordinates of the center of the circle and the size of the radius. Assume that the center coordinates of the scanning field of view are (x1, y1), and the radius is r1, where r1 is obtained by dividing the scanning field of view obtained from the parameter panel by 2; the center coordinates of the extended reconstruction field of view are (x2, y2), and the radius is r2, where r2 is obtained by dividing the extended reconstruction field of view obtained from the parameter panel by 2. Then, a geometric or algebraic method is used to calculate the intersection of the two circles. If the number of intersections of the two circles of the extended reconstruction field of view and the scanning field of view is 0, it means that the extended reconstruction field of view completely contains the scanning field of view. At this time, the circles drawn with the center and radius respectively in the target medical image are used as edge markers. For example, please refer to Figure 3 A first edge marker, namely a green circle 302, is displayed at the edge contour of the extended reconstructed field of view in the target medical image, and a second edge marker, namely a red circle 304, is displayed at the edge contour of the scanned field of view in the target medical image.

[0076] If there are two intersection points of the two circles of the extended reconstruction field of view and the scan field of view, it means that the extended reconstruction field of view and the scan field of view intersect. At this time, it is necessary to calculate the coordinates of the intersection of the two circles, which are intersection point A and intersection point B. Starting from intersection point A, pass through each point on the circumference along the edge contour of the scan field of view until reaching intersection point B. Starting from intersection point B, pass through each point on the circumference along the edge contour of the extended reconstruction field of view until returning to intersection point A. The part from B to A is the edge contour of the extended reconstruction field of view.

[0077] It should be noted that the method of displaying a first edge marker at the edge contour of the extended reconstructed field of view in the target medical image and displaying a second edge marker at the edge contour of the scanned field of view in the target medical image is called a marking display method.

[0078] In the above embodiment, a first edge marker is displayed at the edge contour of the extended reconstruction field of view area in the target medical image, and a second edge marker is displayed at the edge contour of the scanning field of view area in the target medical image. The first edge marker is different from the second edge marker, and can better distinguish the extended reconstruction field of view area and the scanning field of view area, thereby making more accurate diagnosis and treatment decisions.

[0079] In some implementations, the extended reconstruction field of view area and the scanning field of view area are displayed separately, and further include: receiving a preset trigger operation and hiding the boundary mark.

[0080] The preset trigger operation may be a predefined event, and when the event occurs, a specific operation will be triggered.

[0081] Specifically, after the boundary marker is displayed at the junction of the extended reconstruction field of view and the scanning field of view, the user performs a preset trigger operation (such as mouse movement, click, etc.), and the system receives the preset trigger operation, removes the boundary marker from the interface or makes it invisible, and hides the boundary marker displayed on the target medical image.

[0082] In the above implementation, a preset trigger operation is received, the boundary mark is hidden, and a more personalized user experience is provided.

[0083] In some embodiments, see Figure 4 , the method may further include the following steps:

[0084] S410: Receive a preset trigger operation.

[0085] S420: If the receiving position of the preset trigger operation is on the target medical image, the distinguishing mark is hidden.

[0086] S430: After the distinguishing mark is hidden, if a preset trigger operation is received again, the distinguishing mark is displayed again.

[0087] Specifically, after displaying the target medical image including the distinguishing mark, the display mode of the extended reconstructed field of view area in the image is different from the display mode of the scan field of view area. The user performs a preset trigger operation (such as mouse movement, click, etc.), the system receives the preset trigger operation, and detects the position where the preset trigger operation is received. If the receiving position of the preset trigger operation is located on the target medical image, the distinguishing mark is removed from the interface or made invisible, and the distinguishing mark displayed on the target medical image is hidden. After hiding the distinguishing mark, the user performs the preset trigger operation again. The system receives the preset trigger operation again, and then redisplays the distinguishing mark on the target medical image.

[0088] Exemplarily, when the user moves the mouse onto the target medical image, the distinguishing mark is hidden, and then when the user moves the mouse out of the target medical image, the distinguishing mark is displayed again.

[0089] It should be noted that, when a preset trigger operation is received and the receiving position of the preset trigger operation is on the target medical image, the distinguishing mark is hidden. After the distinguishing mark is hidden, if the preset trigger operation is received again, the whole process of redisplaying the distinguishing mark is called the display method of the visible and invisible mark indicator.

[0090] In the above implementation, a preset trigger operation is received. If the receiving position of the preset trigger operation is on the target medical image, the distinguishing mark is hidden. After the distinguishing mark is hidden, if the preset trigger operation is received again, the distinguishing mark is redisplayed, and the display mode of the extended reconstruction field of view area and the scanning field of view area is dynamically adjusted to provide a more personalized user experience.

[0091] In some embodiments, displaying the target medical image may include: when the extended reconstruction field of view area is selected to be hidden, displaying the image of the scanning field of view area in a cropped manner and hiding the image of the extended reconstruction field of view area.

[0092] Specifically, if it is determined that the extended reconstruction field of view area in the target medical image needs to be hidden, an image cropping tool is used to extract the image of the extended reconstruction field of view area from the target medical image, and only the display scanning field of view area is retained, thereby generating a new inspection image and displaying it. Only the display scanning field of view area is displayed in the inspection image, thereby achieving the hiding of the image of the extended reconstruction field of view area.

[0093] In one embodiment, see Figure 5 , Figure 5 Only images showing the scanned field of view are displayed, and Figure 5 The circle 502 in the figure is a distinguishing mark of the extended reconstruction field of view area, and the circle 504 is a distinguishing mark of the scanning field of view area.

[0094] In some embodiments, edge contour detection is first performed on the extended reconstruction field of view and the scanning field of view to identify the junction of the extended reconstruction field of view and the scanning field of view. The area that needs to be cropped is determined by the detected edge contour, i.e., the junction of the extended reconstruction field of view and the scanning field of view. In the case where the extended reconstruction field of view is selected to be hidden, the area that needs to be cropped is the extended reconstruction field of view. The extended reconstruction field of view is extracted from the image, and the scanning field of view is retained, so that the displayed image only contains the image of the scanning field of view, and a new image is generated, thereby hiding the image of the extended reconstruction field of view. In other embodiments, the cropped image can be post-processed, such as adjusting the image size, rotating, edge smoothing, etc.

[0095] In the above implementation, when the extended reconstruction field of view area is selected to be hidden, the image of the scanning field of view area is displayed in a cropped manner, the image of the extended reconstruction field of view area is hidden, and the scanning field of view area is highlighted to reduce interference.

[0096] In some embodiments, displaying the target medical image may include: when the scanning field of view area is selected to be hidden, displaying the image of the extended reconstruction field of view area in a cropped manner and hiding the image of the scanning field of view area.

[0097] Specifically, if it is determined that the scanning field of view area in the target medical image needs to be hidden, an image cropping tool is used to extract the image of the scanning field of view area from the target medical image, and only the extended reconstruction field of view area is retained, thereby generating a new inspection image and displaying it. Only the extended reconstruction field of view area is displayed in the inspection image, thereby hiding the image of the scanning field of view area.

[0098] In some embodiments, see Figure 6a , Figure 6a Only images with an extended reconstruction field of view are displayed, and Figure 6a The circle 602 in the figure is a distinguishing mark for the extended reconstruction field of view area, and the circle 604 is a distinguishing mark for the scanning field of view area.

[0099] In the above implementation, when the scanning field of view area is selected to be hidden, the image of the extended reconstruction field of view area is displayed in a cropped manner, the image of the scanning field of view area is hidden, and the extended reconstruction field of view area is highlighted to reduce interference.

[0100] In some embodiments, see Figure 6b The target medical image includes a first image corresponding to the extended reconstruction field of view area and a second image corresponding to the scanning field of view area. Distinguishing and displaying the extended reconstruction field of view area and the scanning field of view area may include the following steps:

[0101] S610: Receive a preset trigger operation.

[0102] S620: Display or hide at least one of the first image corresponding to the extended reconstruction field of view and the second image corresponding to the scanning field of view.

[0103] Specifically, the user performs a preset trigger operation (such as mouse movement, clicking, etc.), the system receives the preset trigger operation, executes corresponding instructions according to the trigger operation, and displays or hides at least one of the first image corresponding to the extended reconstruction field of view and the second image corresponding to the scanning field of view.

[0104] In the above implementation, a preset trigger operation is received to display or hide at least one of the first image corresponding to the extended reconstruction field of view and the second image corresponding to the scanning field of view, so as to highlight the required information and reduce interference.

[0105] In some embodiments, the target medical image includes a first image corresponding to an extended reconstruction field of view and a second image corresponding to a scanning field of view, and the extended reconstruction field of view and the scanning field of view are displayed separately, including: comparing and displaying the first image and the second image.

[0106] For example, see Figure 7a , displaying the target medical image, which may include:

[0107] S710: Display the extended reconstruction field of view on the first image, and hide the scanning field of view.

[0108] S720: Display the scanned field of view area on the second image, and hide the extended reconstruction field of view area.

[0109] Specifically, after reconstructing the image including the complete data within the scanning field of view and the partial data of the extended reconstruction field of view area, and obtaining an image including the scanning field of view area and the extended reconstruction field of view area, it is necessary to display the scanning field of view area and the extended reconstruction field of view area respectively on the same image. Therefore, the image can be divided into two parts, the first part is called the first image, and the second part is called the second image. On the first image, only the extended reconstruction field of view area is displayed, and the scanning field of view area is not displayed, so as to achieve the hiding of the scanning field of view area. On the second image, the scanning field of view area is displayed, and the extended reconstruction field of view area is not displayed, so as to achieve the hiding of the extended reconstruction field of view area.

[0110] In some embodiments, a medical image showing a first edge marker at the edge contour of the extended reconstruction field of view region and a second edge marker at the edge contour of the scanning field of view region is cropped to extract the extended reconstruction field of view region, retain the scanning field of view region, and obtain a second image. A medical image showing a first edge marker at the edge contour of the extended reconstruction field of view region and a second edge marker at the edge contour of the scanning field of view region is cropped to extract the scanning field of view region, retain the extended reconstruction field of view region, and obtain the first image. The first image and the second image are displayed on the same image. For example, see Figure 7b , Figure 7b The rectangular frame 702 in FIG. 7 is the second image. Figure 7b The rectangular frame 704 in FIG. 7 is the first image.

[0111] In the above embodiment, the extended reconstruction field of view area is displayed on the first image and the scanning field of view area is hidden, and the scanning field of view area is displayed on the second image and the extended reconstruction field of view area is hidden, so that the extended reconstruction field of view area and the scanning field of view area are effectively displayed and utilized to provide more comprehensive diagnosis and analysis.

[0112] In some embodiments, the method may further include: displaying a boundary mark at a junction of the extended reconstruction field of view area and the scanning field of view area.

[0113] Specifically, when the first image corresponding to the reconstruction field of view or the second image corresponding to the scanning field of view is hidden, the boundary mark is still displayed at the junction of the extended reconstruction field of view and the scanning field of view.

[0114] In some embodiments, see Figure 5 When the first image corresponding to the reconstruction field of view is hidden, a boundary mark 504 is displayed at the junction of the extended reconstruction field of view and the scanning field of view.

[0115] In some other embodiments, please refer to FIG. 6 , when the second image corresponding to the scanning field of view area is hidden, a boundary mark 604 is displayed at the junction of the extended reconstruction field of view area and the scanning field of view area.

[0116] In some implementations, the method may further include: adjusting display information of the first image and the second image independently of each other.

[0117] The display information may be a visual presentation effect of an image.

[0118] Specifically, the user can adjust the brightness, contrast, display angle and other parameters of the first image, and display the image according to the adjusted parameters to determine the display information of the first image. The user can adjust the brightness, contrast, display angle and other parameters of the second image, and display the image according to the adjusted parameters to determine the display information of the first image.

[0119] Exemplarily, the window width and window position of the image of the scanned field of view area and the image of the expanded reconstructed field of view area can be adjusted independently of each other.

[0120] Specifically, the window width and window position can be used to adjust the key parameters of the grayscale display range and brightness distribution. The window width determines the contrast of the image. A larger window width will reduce the contrast and is suitable for displaying structures with a wide grayscale range; while a smaller window width will enhance the contrast and is suitable for highlighting details in a specific grayscale value range. The window position is the center position of the window width. Adjusting the window position can change the overall brightness of the image, which helps to highlight the tissue or structure of interest. Different window widths and window positions are set independently for different fields of view, that is, the window width and window position of the image in the scanned field of view area can be adjusted independently of each other, and the window width and window position of the image in the extended reconstructed field of view area can be adjusted independently of each other without interfering with each other. By adjusting the window width and window position independently for each area, the display effect of the image can be optimized to better observe the effects of specific anatomical structures or pathological features.

[0121] In the above implementation, the window width and window position of the image of the scanned field of view area and the image of the expanded and reconstructed field of view area can be adjusted independently of each other, so as to be flexibly adjusted to suit different scenes.

[0122] In some embodiments, see Figure 8 Different scanning parts correspond to different distinguishing display modes; the method also includes the following steps:

[0123] S810: Determine a scanning part corresponding to the target medical image.

[0124] S820: Determine a display method for distinguishing the extended reconstruction field of view area from the scan field of view area based on the scanned part.

[0125] Specifically, after the extended reconstruction field of view imaging function is turned on (which can be controlled by a switch), different display protocols and preset parameters are designed and adjusted for each scanning part according to different scanning parts and specific needs. First, by determining the scanning part corresponding to the target medical image, an appropriate distinguishing display method is selected. The complete data collected for the current scanning part, including the scanning field of view and the partial data of the extended reconstruction field of view area, are reconstructed to obtain an image including the extended reconstruction field of view area and the scanning field of view area. According to the preset distinguishing display method corresponding to the current scanning part, the extended reconstruction field of view area and the scanning field of view area are distinguished and displayed.

[0126] Exemplarily, the preset differentiation display mode sets different display options according to the scanning part. In the parameter panel or system setting interface, it supports configuring the correspondence between the scanning part and the preset differentiation display mode. By default, the heart area is set to the display mode of the visible and invisible identification indicator by default. The abdominal area is set to the display mode of the mark display by default. The head area is not configured with a preset differentiation display mode. In clinical applications, if it is necessary to switch the preset differentiation display mode, the operator can manually adjust the preset differentiation display mode of the scanning part and adjust the default display mode to other forms of display. If the adjusted preset differentiation display mode meets clinical needs, it can be saved and shared for use in other clinical applications.

[0127] In the above implementation, the scanning part corresponding to the target medical image is determined, and based on the scanning part, the distinguishing display method of the extended reconstruction field of view area and the scanning field of view area is determined, providing a more reliable basis for clinical diagnosis and treatment.

[0128] In some implementations, determining a scanned portion corresponding to a target medical image may include:

[0129] A scanning protocol corresponding to the target medical image is obtained, and a scanning part is determined based on the scanning protocol.

[0130] The scanning protocol includes scanning part information.

[0131] Specifically, a scanning protocol of a target medical image is obtained from a medical imaging system. The scanning protocol generally includes specific scanning parameters and operation steps, which are used to guide medical imaging technicians to perform scanning. The scanning protocol is parsed to identify the scanning part covered by the target medical image.

[0132] In some implementations, determining a scanned portion corresponding to a target medical image may include:

[0133] The target medical image is input into the part recognition model for recognition to determine the scanning part.

[0134] Specifically, the target medical image is used as the input of the input part recognition model, and the target medical image is recognized and processed by the input part recognition model to determine the scanning part included in the target medical image.
