Description

Technical Field

[0001] This invention relates to the field of image processing technology, and in particular to an image comparison system, an image comparison method, and their applications. Background Technology

[0002] To facilitate the use of the mobile X-ray machine 1 during surgery, the display system of the mobile X-ray machine generally includes a monitoring screen 11 for doctors to monitor and observe images, and an operation screen 12 for technicians to operate the instrument and project images onto the monitoring screen 11, such as... Figure 1 As shown.

[0003] When doctors use a mobile X-ray machine to acquire images for diagnostic analysis during surgery, they need to compare and analyze images of the same surgical area from different angles. The technician needs to select the required reference and comparison images on the control screen according to the doctor's instructions, and then project these images onto the monitoring screen 11 for the doctor to see. The doctor then observes and compares the two images on the monitor.

[0004] Currently, the display layout of the operator panel 12 on existing mobile X-ray machines differs significantly from that of the monitoring panel 11, such as... Figure 2 As shown, monitor 11 is a dual-image display area, while operation screen 12 has only a single-image display area. The single-image display area of ​​operation screen 12 is synchronized with the left area of ​​monitor 11. In practical application, the specific operation process is as follows: ① The technician selects images one by one from the list and displays them in the single-image display area of ​​operation screen 12, ② and projects them onto the left area of ​​monitor 11. The doctor selects a suitable reference image by browsing, ③ and issues an instruction to the technician to project the reference image onto the right area of ​​monitor 11. This is the process of selecting and projecting the reference image. Afterward, the technician selects images one by one from the list and displays them in the single-image display area of ​​operation screen 12 and projects them onto the left area of ​​monitor 11, until the doctor selects a suitable comparison image by browsing the images in the left area of ​​monitor 11. The technician then stops image projection, and the doctor begins comparative observation.

[0005] This leads to the following problems when technicians project images according to the doctor's needs:

[0006] 1. The technician needs to project the reference image first onto the single-image display area of ​​the operation screen 12, then synchronize it to the left area of ​​the monitoring screen 11, and then project it onto the right area of ​​the monitoring screen 11. That is, at least three steps are required. Figure 2 As shown, the process must be relayed through the left area of ​​monitoring screen 11, making the entire operation cumbersome and time-consuming. When the reference image needs to be replaced, the above steps must be repeated, making the operation even more cumbersome.

[0007] 2. Doctors can only determine the reference image by observing the projected images in the left area of ​​the monitoring screen 11 one by one. The information seen by doctors and technicians is inconsistent. Doctors cannot see the full picture of all the images. When there are many images, they need to observe many images before they can make a selection. It is difficult to remember all the images and select the most suitable reference image from them. In most cases, technicians need to operate repeatedly several times to meet the doctor's needs, which is inefficient.

[0008] 3. Both doctors and technicians need to be familiar with the instrument's image projection and display operation procedures, and a high level of communication and cooperation between doctors and technicians is required. If any problem occurs in the operation or communication at any step, it is necessary to go back and search for the image again. Summary of the Invention

[0009] Purpose of the invention: To address the above-mentioned shortcomings, this invention proposes an image comparison system, an image comparison method, and their applications. The system offers high operational accuracy, conforms to cognitive and behavioral habits, is less prone to errors, reduces the user's familiarity with the instrument and the degree of cooperation required, and significantly improves the user's experience with the instrument.

[0010] Technical solution:

[0011] Image comparison system, including:

[0012] The acquisition module is used to acquire operation instructions;

[0013] The display module includes at least two display modules, each of which is connected to the processing module.

[0014] The processing module is connected to the acquisition module and processes the partitions and images of the at least two display modules according to the acquired operation instructions, and the partitions of the at least two display modules are synchronized accordingly.

[0015] Specifically, the partition includes at least one of a reference area for presenting a reference image, a comparison area for presenting a comparison image, and a list area for listing all images.

[0016] More specifically, the processing module includes:

[0017] The first receiving unit, connected to the acquisition module, is used to receive the comparison function enabling instruction;

[0018] An extension unit connects the first receiving unit and the display module, and synchronously partitions the display interface of the display module according to the function opening instruction.

[0019] Furthermore, the expansion unit is also connected to the image memory of the image acquisition device, and is used to retrieve images from the image memory and project them onto the list area.

[0020] Furthermore, in the display interface of the display module, the list area is vertically positioned between the comparison area and the reference area.

[0021] Furthermore, in the display interface of the display module, the list area is horizontally positioned above or below the comparison area and the reference area.

[0022] Furthermore, the comparison area is aligned with the reference area, and the list area can be hiddenly placed at the edge of the comparison area or the reference area.

[0023] Furthermore, the processing module also includes:

[0024] The second receiving unit is connected to the acquisition module and is used to receive the image selection instruction and projection instruction in the operation instructions acquired by the acquisition module.

[0025] The projection unit connects the second receiving unit and the display module, and projects the selected image according to the image selection instruction and the projection instruction, projecting the image selected by the user in the list area to the comparison area or reference area of ​​the display module.

[0026] Furthermore, the processing module also includes:

[0027] The third receiving unit is connected to the acquisition module and is used to receive the comparison instruction from the operation instruction acquired by the acquisition module.

[0028] The hidden unit connects the third receiving unit and the display module, and adjusts the display area of ​​the display module according to the comparison instruction to make the comparison area and the reference area similar.

[0029] Furthermore, the partitioning adjustment involves hiding, edge-setting, or shrinking the list area to bring the comparison area and the reference area closer together or make them fit together.

[0030] Furthermore, the list area is hidden, and the space at the corresponding position on the display module is filled by proportionally enlarging the comparison area or by simultaneously enlarging and filling the comparison area and the reference area proportionally.

[0031] Furthermore, the display module includes a first display module connected to the processing module for the operator to send operation commands and a second display module for the observer to observe and compare images.

[0032] The processing module also includes a synchronization unit;

[0033] The expansion unit, projection unit, and hiding unit are all connected to the first display module and to the second display module through the synchronization unit. After the acquisition module obtains the comparison function opening instruction, it performs synchronization processing on the partitions and projected images of the second display module, so that the partitions and images presented by the first display module and the second display module are consistent.

[0034] Specifically, the acquisition module is a virtual touch key on the display module.

[0035] Furthermore, before receiving the comparison function enable command, a comparison function enable touch button is displayed on the display module.

[0036] After receiving the image selection command, directional projection touch keys appear on both sides of the list area or on both sides of the selected image, which are used by the user to trigger the projection command.

[0037] Furthermore, after both the reference image and the comparison image are projected, a list-hiding touch button is displayed on the display module.

[0038] An image comparison method includes the following steps:

[0039] (1) Obtain the comparison function opening instruction, and perform partitioning processing on at least one display module according to the comparison function opening instruction, so that the partition presents at least one of the reference area, the comparison area and the list area;

[0040] (2) Obtain the projection instruction and project the selected image in the list area to the comparison area or reference area according to the projection instruction.

[0041] Specifically, it also includes step (3):

[0042] Obtain a comparison instruction, and perform partition adjustment processing on the display module according to the comparison instruction to make the comparison area and the reference area similar.

[0043] More specifically, the partitioning adjustment involves hiding the list area and enlarging and filling the comparison area and / or the reference area so that the comparison area fits the reference area.

[0044] Furthermore, the partitioning adjustment involves shrinking the list area and enlarging and filling the comparison area and / or the reference area, so that the comparison area is closer to the reference area.

[0045] Furthermore, the display module includes a first display module and a second display module, and the projection process enables the contrast area of ​​each display module to synchronously display a contrast image, and / or the reference area to synchronously display a reference image.

[0046] Furthermore, the selection of the reference image displayed in the reference area is determined by the first user browsing in the list area of ​​the second display module, and then the second user is commanded to perform the selection and projection operation in the first display module.

[0047] Alternatively, the second user can select items sequentially from the list area of ​​the first display module and project them, after which the first user can make the selection.

[0048] Alternatively, a second user can simultaneously project two similar images onto the comparison area and reference area of ​​the first display module and the second display module, respectively. The first user can then compare and select the images, and the second user can then simultaneously project them onto the reference area of ​​the first display module and the second display module.

[0049] A computer storage medium storing a computer program, which, when executed, implements the steps of the image comparison method described above.

[0050] A C-arm camera, the C-arm camera including an image comparison system as described above, and / or a computer storage medium as described above.

[0051] Beneficial effects:

[0052] 1. This invention, by setting up a comparison area, a reference area, and a list area that are displayed synchronously in at least two display modules, and by allowing interactive methods such as freely projecting images from the image list area to the comparison area or the reference area, enables doctors and technicians to maintain a high degree of consistency in reading and recognizing image information and simplifies operation steps. It also reduces the requirements for users' familiarity with the instrument and their coordination with each other, and can greatly improve the user's experience with the instrument.

[0053] 2. This invention can directly project the reference image to the right onto the reference area and the comparison image to the left onto the comparison area (or without any changes), without the need for an intermediate conversion process. It can be done in one step, with high operational accuracy, convenient image replacement, and conforms to cognitive behavior habits, making it less prone to errors. Attached Figure Description

[0071] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0072] This invention provides an image comparison system, such as... Figure 3 As shown, the image comparison system 2 includes:

[0073] The acquisition module 21 is used to acquire user operation commands; the operation commands include commands to enable the comparison function, image selection, and projection. Optionally, it also includes comparison commands.

[0074] Optionally, the acquisition module 21 acquires the user's operation instructions through the virtual touch keys on the touch screen terminal (i.e., the display module 23) and sends them to the processing module 22.

[0075] Specifically, the projection command can be either a directional movement command or an arbitrary drag command.

[0076] Optionally, the acquisition module may also be, but is not limited to, physical buttons on the display module 23, such as physical buttons on the front of the display module 23 excluding the display interface area, physical buttons on the side or back of the display module 23, etc.

[0077] The processing module 22, connected to the acquisition module 21, is used to process the display area of ​​the display module 23 according to various operation instructions acquired by the acquisition module 21, including partitioning the display area of ​​the display module 23 according to the comparison function opening instruction, retrieving the image acquired by the image acquisition device according to the image selection instruction, and performing projection processing according to the projection instruction.

[0078] The display module 23 includes a first display module 231 and a second display module 232. Both the first display module 231 and the second display module 232 are connected to the processing module 22 and are used to synchronously present the partition and the projected image.

[0079] Furthermore, such as Figure 4 As shown, the processing module 22 includes:

[0080] The first receiving unit 221 and the expansion unit 222 are connected to the acquisition module 21 and receive the comparison function opening instruction. The expansion unit 222 is connected to the first receiving unit 221 and the first display module 231. According to the received comparison function opening instruction, the display interface of the first display module 231 is divided into a comparison area 2311, a list area 2312, and a reference area 2313. The comparison area 2311 is used to present the selected comparison image, the reference area 2313 is used to present the selected reference image, and the list area 2312 is used to list all images. Specifically, the list area 2312 is used to list all images sorted in chronological order. The expansion unit 222 is also connected to the image storage 24 of the image acquisition device and is used to retrieve the images in the image storage 24 and project them onto the list area for the user to browse and select.

[0081] Optionally, such as Figure 4 As shown, the list area 2312 is located between the comparison area 2311 and the reference area 2313. The list area 2312 is designed to be vertical, that is, the images in the list area 2312 are displayed by sliding in the vertical direction, making the comparison area 2311 and the reference area 2313 more distinct.

[0082] Optionally, such as Figure 5 As shown, the list area 2312 is located above or below the comparison area 2311 and the reference area 2313. The list area 2312 is designed to be horizontal, that is, the images in the list area 2312 are displayed by sliding in the horizontal direction.

[0083] In this invention, the display interface of the second display module 232 can be designed to be the same as that of the first display module 231, divided into a comparison area 2321, a list area 2322, and a reference area 2323;

[0084] Furthermore, the image acquisition device of the present invention is, but is not limited to, a mobile C-arm X-ray machine. The first display module 231 is the operation screen 12 of the image acquisition device, which is used by the technician to send operation instructions and project images onto the monitoring screen 11. The second display module 232 is the monitoring screen 11 of the image acquisition device, which is used by the doctor to facilitate the doctor's observation and comparison of images.

[0085] In this invention, the processing module 22 further includes a second receiving unit 223 and a projection unit 224. The second receiving unit 223 is connected to the acquisition module 21 and receives the image selection instruction and projection instruction sent by the acquisition module 21. The projection unit 224 is connected to the second receiving unit 223 and the first display module 231 and projects the selected image in the list area 2312 according to the received image selection instruction and projection instruction, and projects the image selected by the user in the list area 2312 to the comparison area 2311 or reference area 2313 of the first display module 231.

[0086] Optionally, the processing module 22 further includes a third receiving unit 225 and a hiding unit 226. The third receiving unit 225 is connected to the acquisition module 21 and receives the comparison instruction acquired by the acquisition module 21. The hiding unit 226 is connected to the third receiving unit 225 and the first display module 231 and adjusts the display area of ​​the display module 23 according to the received comparison instruction, so that the comparison area 2311 and the reference area 2313 are close to or attached to each other.

[0087] Optionally, such as Figure 6 , 8As shown, the partitioning adjustment involves hiding or edge-setting the list area 2312 to ensure that the comparison area 2311 and the reference area 2313 are completely aligned, facilitating seamless comparison and observation of the reference and comparison images. When the list area 2312 is hidden, the space at corresponding positions on the first display module 231 and the second display module 232 can be filled by proportionally enlarging the comparison area or by simultaneously enlarging both the comparison and reference areas proportionally, ensuring that the comparison area aligns with the reference area and that the image fully occupies the display interface of the display module 23. Alternatively, the displayed list area can be placed at the edge of the comparison area, and after the list area is collapsed, the portion of the comparison area covered by it can be displayed, ensuring that the comparison area aligns with the reference area.

[0088] Optionally, such as Figure 7 As shown, partitioning adjustment also includes, but is not limited to, shrinking the list area to bring the comparison area and reference area closer together for easier comparison and observation by the user.

[0089] The processing module 22 also includes a synchronization unit 227, wherein the expansion unit 222, the projection unit 224, and the hiding unit 226 are all connected to the first display module 231, and are also connected to the second display module 232 through the synchronization unit 227, so as to process the partitions and projected images of the display interface of the second display module 232, so that the partitions and images presented by the first display module 231 and the second display module 232 are consistent.

[0090] In the case where the user's operation command acquired by the acquisition module 21 is sent via virtual touch keys on the display module 23, optionally, as follows: Figure 9 As shown, before the user issues a comparison function enable command, the first display module 231 also presents a comparison function enable touch button 2314, which is used by the user to trigger the sending of the comparison function enable command. After the user issues an image selection command, the selected image in the list area of ​​the display module is marked, and directional projection touch buttons, specifically directional projection marks 2315, are also presented on both sides of the list area 2312 or on both sides of the marked image, which are used by the user to trigger a projection command. Optionally, after both the reference image and the comparison image have been projected, a list hide touch button 2316 is automatically presented, or a list hide touch button 2316 is always presented on one side of the list area 2311, through which the user expresses the intention to hide the list to the acquisition module 21.

[0091] After the user gives the instruction to enable the comparison function, the image comparison system 2 refers to... Figure 9The display interfaces of the first display module 231 and the second display module 232 both include a comparison area, a reference area, and a list area. The images projected in the comparison area and reference area of ​​both modules are synchronized with the images listed in the list area, so that the image information viewed by the technician and the doctor is synchronized. The technician selects an image in the list area 2312 of the first display module 231 and projects it to the comparison area 2311 or the reference area 2313. The corresponding image in the list area 2322 on the display interface of the second display module 232 is synchronously projected to its corresponding area.

[0092] Before the comparison function is enabled, the right side of the display interface of the first display module 231 is the operation interface, such as... Figure 9 As shown in Figure (a); when an image comparison operation is required, the user presses the comparison function enable touch key 2314 to send a comparison function enable command to the processing module 22. The processing module 22 controls the right area of ​​the display interface of the first display module 231 to be replaced by the reference area 2313. At the same time, the processing module 22 controls the display interface of the second display module 232 to be replaced by the reference area 2323, the list area 2322, and the comparison area 2321, and the location is consistent with the first display module 231. The images in the list area 2313 and the comparison area 2311 of the first display module 231 are always consistent with the list area 2323 and the comparison area 2321 of the second display module 232, as shown in Figure (a). Figure 9 As shown in Figure (b), the user selects and projects reference and comparison images in the list area 2313 of the first display module 231. The processing module 22 controls the second display module 232 to perform corresponding synchronous projection through the synchronization unit 227. Figure 9 As shown in Figure (c), the list area 2313 in the first display module 231 is hidden, and the processing module 22 controls the list area 2313 in the second display module 11 to be hidden accordingly, as shown in Figure (c). Figure 9 As shown in Figure (d).

[0093] All of the above can ensure that doctors and technicians maintain a high degree of consistency in reading and recognizing image information, simplify operating procedures, reduce the requirements for users' familiarity with the instrument and their cooperation, and greatly improve the user's experience with the instrument.

[0094] The present invention also provides an image comparison method, based on the aforementioned image comparison system, such as... Figure 10 As shown, the steps include:

[0095] S1. Obtain the comparison function opening instruction, and perform partitioning processing on the first display module 231 and the second display module 232 according to the instruction. The first display module 231 displays the reference area 2313, the comparison area 2311 and the list area 2312, and the second display module 232 synchronously displays the reference area 2323, the comparison area 2321 and the list area 2322.

[0096] Furthermore, before the user issues the command to enable the comparison function, the first display module 231 also presents the comparison function enable touch button 2314, such as... Figure 9 As shown in Figure (a), the comparison function enable command is obtained by the user touching the comparison function enable touch key 2314.

[0097] Furthermore, the list area displays images stored in the image memory; more specifically, the list area displays images according to the acquisition sequence of the images stored in the image memory.

[0098] Specifically, such as Figure 9 As shown, before the comparison function is enabled, the right area of ​​the first display module 231 is the operation interface, and the left area includes the comparison area and the list area. The second display module 232 is a single-image display interface, as shown below. Figure 9 As shown in Figure (a), after the user issues the command to enable the comparison function, the processing module 22 replaces the operation interface of the right area of ​​the first display module 231 with the reference area; the single image display area of ​​the second display module 232 shrinks to the left to become the comparison area, and then the empty area is displayed as the list area and the comparison area, so that the comparison area, the list area and the reference area are displayed synchronously on the first display module 231 and the second display module 232.

[0099] S2. Obtain the projection instruction, and according to the instruction, project the selected image in the list area of ​​the first display module 2321 to the comparison area or reference area. The reference area and comparison area of ​​the first display module 231 and the second display module 232 synchronously display the selected reference image and comparison image.

[0100] Furthermore, after the user issues a command to enable the comparison function, the first display module 231 displays directional movement function touch keys on both sides of the list area or on both sides of the marked image, such as directional projection markers, etc. Figure 9 As shown in Figure (b), the projection command is obtained by the user touching the projection direction marker.

[0101] Specifically, such as Figures 9-11 As shown, according to the doctor's instructions, the technician selects an image from the list area of ​​the first display module 231 as a reference image and projects it synchronously to the reference areas of the first display module 231 and the second display module 232 through the directional projection mark. The technician also selects an image from the list area of ​​the first display module 231 as a comparison image and projects it synchronously to the comparison areas of the first display module 231 and the second display module 232 through the directional projection mark.

[0102] The technician slides the images vertically in the list area on the first display module 231 and selects one image to project onto the comparison area or reference area. If the technician or doctor determines that the image being projected is a reference image, the technician controls (such as a direction projection marker) to simultaneously project it onto the reference area of ​​the first display module 231 and the second display module 232. If the technician or doctor determines that the image is a comparison image, the technician controls (such as a direction projection marker) to simultaneously project it onto the comparison area of ​​the first display module 231 and the second display module 232.

[0103] In this step, the reference image can be selected by the doctor from the thumbnails in the list area and then informed to the technician, who will then select and project it in the first display module 231; alternatively, the technician can select images from the list area one by one for projection and display, and then the doctor can make the selection; even more specifically, the technician can simultaneously project two similar images to the comparison area and reference area of ​​the first display module 231 and the second display module 232, respectively, so that the doctor can compare and select the better reference image, and then the technician can project it to the reference area of ​​the first display module 231 and the second display module 232.

[0104] Furthermore, if the doctor believes that a certain image needs to be replaced, the technician selects the replacement image from the list area of ​​the first display module 231, projects it, and the processing module 22 projects it and covers the corresponding area.

[0105] In this invention, the directional projection mark on the first display module 231 can also be replaced with, but is not limited to, a directional drag prompt. The image projection operation can be performed by a technician dragging the image on the first display module 231 to the corresponding display area, or by selecting an image on the first display module 231, where corresponding arrows pointing to the corresponding display areas are displayed on the image, and projection is controlled by clicking the corresponding arrows. The projection unit 224 then projects the image synchronously to the corresponding display areas of the first and second display modules 231.

[0106] This invention can directly project the reference image to the right onto the reference area and the comparison image to the left onto the comparison area (or without any changes), without the need for an intermediate conversion process; doctors can see the full picture of all images, making it easier to select images; and doctors and technicians have the same view, which facilitates communication and reduces the likelihood of errors.

[0107] Optional, such as Figure 11 As shown, the image comparison method of the present invention further includes:

[0108] S3. Obtain a comparison instruction, and perform partition adjustment processing on the first display module 231 and the second display module 232 according to the instruction. The partition adjustment includes partition ratio adjustment and / or partition position adjustment, especially the adjustment of the list area, including hiding or shrinking the list area, and the reference area and comparison area of ​​the first display module 231 and the second display module 232 are adjacent or attached.

[0109] Furthermore, a list-hiding touch button 2316 is displayed on one side of the list area of ​​the first display module 231, such as... Figure 9 As shown in Figure 9(b) or Figure 9(c), the projection command is obtained by the user touching the list hiding touch key 2316.

[0110] Specifically, the technician sends a comparison instruction to the processing module via the list-hide touch button 2316 on the first display module. The processing module then simultaneously hides the list areas of both the first and second display modules, making the comparison area and the reference area adjacent. Figure 9 As shown in Figure (d), the image information on the first display module and the second display module is consistent at this time, and the observer compares and analyzes the image information in the comparison area and the reference area on the second display module.

[0111] Furthermore, when the list area is collapsed or hidden, the comparison area and the reference area fit together seamlessly. The list area can also be displayed in a proportionally scaled-down manner or tucked to the edge of a display area.

[0112] This invention, through a first display module 231 and a second display module 232 that synchronously display a comparison area, a reference area, and a list area, ensures a high degree of consistency in the layout and status of the real-time comparison image information, reference image information, and thumbnail images in the list area observed by observers such as doctors and technicians. This simplifies operation steps, improves the accuracy and efficiency of communication between doctors and technicians. When the list area of ​​the first display module 231 expands, the list area on the second display module 232 expands synchronously; when the list area of ​​the first display module 231 collapses, the list area on the second display module 232 collapses synchronously. Technicians can also collapse the reference area on the first display module 231, restoring the normal usage mode with only the comparison area, such as... Figure 9 As shown in Figure (a). It should be noted that the first display module 231 and the second display module 232 can be used separately or in combination according to actual needs. This case mainly describes the case of combined use. Similarly, the reference area and list area in the display module 23 can also be used separately or in combination according to actual needs. This case mainly describes the case of combined use.

[0113] In this invention, the list area and its dual-screen synchronization allow both users (doctors and technicians) to intuitively select images for comparison within a single interface. The information is consistent, and the selected images can be quickly replaced without switching between image selection and image processing interfaces. This allows for a one-step process with high operational accuracy, conforms to cognitive behavior habits, and eliminates the need for real-time switching from the screen to the reference area, effectively preventing incorrect selections. Even if an incorrect selection is made, it can be quickly overwritten and replaced. This allows the operator to quickly meet the observer's needs and reduce operational errors. Furthermore, the observer can easily view the overall images and intuitively select the reference image.

[0114] Furthermore, such as Figure 12 As shown, the present invention further includes step S0 before step S1:

[0115] Step S0: The image acquisition device acquires target images and stores them in the image storage device. Multiple target images are generated; the target can be, but is not limited to, images of human tissue, such as a spinal image. During the image acquisition stage, the partitions of the first display module 231 and the second display module 232 are not synchronized. The first display module 231 also displays the operation interface for the technician to operate the instrument.

[0116] Step S3 is followed by step S4:

[0117] The processing module 22 also includes a comparison termination unit (not shown in the figure), which is used to close the comparison function and simultaneously desynchronize the partitions and images of the first and second display modules according to the user operation instructions (such as the comparison function closing instruction) obtained by the acquisition module 21.

[0118] In this invention, the first and second display modules are synchronized only during the continuous period when the image comparison function is open, and are asynchronous during the use of other image acquisition devices. The first and second display modules are controlled separately by the processing module at 22 minutes, which can make efficient and differentiated use of the first and second display modules and eliminate the problem of invalid occupation of the display interface.

[0119] Specifically, the present invention also provides a computer storage medium storing a computer program, which, when executed, implements the steps of the aforementioned image comparison method.

[0120] Furthermore, the present invention also provides a C-arm machine, which includes the aforementioned image comparison system and / or the aforementioned computer storage medium.

[0121] This invention, by setting up a synchronously displayed comparison area, reference area, and list area on the display module, and by allowing interactive methods such as freely projecting images from the image list area to the comparison or reference area, enables doctors and technicians to maintain a high degree of consistency in reading and recognizing image information, simplifies operation steps, reduces the requirements for user familiarity with the instrument and mutual cooperation, and significantly improves the user experience. Furthermore, the operation is seamless, highly accurate, and convenient, conforming to cognitive behavioral habits and reducing the likelihood of errors.

[0122] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations (such as quantity, shape, position, etc.) can be made to the technical solution of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
