[0033] Before introducing the embodiments of the present application, an exemplary description of the registration interaction interface used in the embodiments of the present application is first given to better understand the interface interaction process described in the following embodiments.

[0034] Exemplarily, as shown in Figures 1a and 1b, an angiography image area and an intracavitary image area are provided on the registration interactive interface, wherein the angiography image area includes an angiography image display area (as shown in the upper left of Figure 1a), an angiography image branch map area (as shown in the middle left of Figure 1a and the upper left of Figure 1b), and an angiography image vascular diameter map area (as shown in the lower left of Figure 1a and the lower left of Figure 1b), and the intracavitary image area includes an intracavitary image cross-section area (as shown in the upper right of Figure 1a), an intracavitary image longitudinal section area (as shown in the middle right of Figure 1a and the upper right of Figure 1b), and an intracavitary image vascular diameter map area (as shown in the lower right of Figure 1a and the lower right of Figure 1b).

[0035] In the angiography image display area, a digital subtraction angiography (DSA) image of the target blood vessel (hereinafter referred to as the angiography image), the blood vessel contour of the registration segment on the target blood vessel (i.e., the contour represented by the white dotted line in Figure 1a), and an index mark used to mark the index position of the target blood vessel (such as the line represented by the white solid line in Figure 1a, such an index mark may also be called an index line) may be displayed.

[0036] In the angiographic branch map area, the vessel length of the target vessel, the side branch marker used to mark the position of the side branch on the target vessel (such as the black square in Figure 1a and the gray square in Figure 1b), the index marker (such as the black vertical straight line in Figure 1a and the white vertical straight line in Figure 1b), and the registration marker used to identify the registration segment (such as the black horizontal dotted line in Figure 1a) can be displayed.

[0037] In the angiographic vessel diameter map area, the vessel diameter of the target vessel, the quantitative flow fraction (QFR) pullback curve (such as the curve in Figure 1b), and the index mark (the black vertical line in Figure 1a and the white vertical line in Figure 1b) can be displayed.

[0038] In the intraluminal image cross-section area, the intraluminal image cross-section and vascular contour of the target blood vessel can be displayed. In practical applications, the intraluminal image can optionally be obtained through intravascular imaging technology, such as optical coherence tomography (OCT) technology or intravascular ultrasound (IVUS) technology.

[0039] In the longitudinal section area of ​​the intracavitary image, the longitudinal section of the intracavitary image, the side branch marks (such as ①-⑤ in Figure 1a and Figure 1b), the index mark (such as the black longitudinal solid line in Figure 1a and the white longitudinal straight line between ② and ③ in Figure 1b) and the registration mark (such as the black longitudinal dotted line in Figure 1a and the white longitudinal straight line located on the left of ① and on the right of ⑤ in Figure 1b) can be displayed.

[0040] In the intraluminal image vessel diameter map area, the vessel diameter and index mark (such as the black vertical straight line in FIG. 1 a and the white vertical straight line in FIG. 1 b ) may be displayed, and the vessel diameter corresponding to the non-registered segment is 0.

[0041] The image data displayed in the angiographic image area and the intracavitary image area described above can be controlled by the controller in FIG. 1 c .

[0042] FIG2 is a flow chart of an interactive method for registration of angiography and intracavitary images provided in an embodiment of the present application. This embodiment is applicable to situations where the registration effect between angiography images and intracavitary images is demonstrated. The method can be performed by an interactive device for registration of angiography and intracavitary images provided in an embodiment of the present application. The device can be implemented in software and / or hardware, and the device can be integrated into an electronic device, which can be various user terminals or servers.

[0043] Referring to FIG. 2 , the method according to the embodiment of the present application may include the following steps:

[0044] S110. Display the angiographic image data of the target blood vessel in the angiographic image area on the registration interaction interface, wherein the angiographic image data at least includes a first index mark that marks an index position of the target blood vessel.

[0045] In some embodiments, the registration interaction interface can be understood as a pre-set interface that can be used to display the registration effect between the angiographic image and the intracavitary image. For example, it can be understood as an interface that can display the registration effect through interface interaction.

[0046] An angiography image area is provided on the registration interaction interface. The angiography image area can be understood as an area used to display the angiography image data of the target blood vessel. For example, it can be at least one of the angiography image display area, the angiography image branch map area, and the angiography image blood vessel diameter map area described above. Of course, it can also be other areas that can be used to display angiography image data.

[0047] The angiographic image data can be understood as data related to the angiographic image of the target blood vessel, for example, it can be at least one of the angiographic image, blood vessel contour, index mark, blood vessel length, side branch mark, registration mark, blood vessel diameter and QFR retracement curve exemplified above, and of course, it can also be other data related to the angiographic image.

[0048] In the contrast image area, contrast image data is displayed.

[0049] On this basis, it should be emphasized that, first, the angiographic image data in the embodiment of the present application includes at least an index identifier, and in order to facilitate the distinction between the index identifier obtained based on the angiographic image and the index identifier obtained based on the intracavitary image described later, the former is referred to as the first index identifier and the latter is referred to as the second index identifier. This method of distinguishing by "first" and "second" can also be applied to other concepts involved in both angiographic images and intracavitary images, such as registration identifiers and side branch identifiers.

[0050] Second, taking the index mark as an example, in actual applications, the index mark can be represented in a variety of ways, such as patterns, text or numbers, etc. On this basis, for patterns, for example, it can be a point (such as a solid point or a hollow point), a line (such as a straight line or a curve, a solid line or a dotted line, a horizontal line or a vertical line) or a surface (such as a solid frame or a hollow frame). In other words, the index mark is mainly used to identify the index position, and the expression method of the index mark can be determined according to the actual situation. In addition, the above description also applies to other types of marks, such as registration marks and side branch marks.

[0051] S120. Display the intracavity image data of the target blood vessel in the intracavity image area on the registration interaction interface, wherein the intracavity image data at least includes a second index mark marking the index position.

[0052] In some embodiments, an intraluminal image area is provided on the registration interaction interface. The intraluminal image area can be understood as an area for displaying the intraluminal image data of the target blood vessel. For example, it can be at least one of the intraluminal image cross-section area, the intraluminal image longitudinal section area, and the intraluminal image blood vessel diameter map area described above. Of course, it can also be other areas that can be used to display intraluminal image data.

[0053] Intraluminal image data can be understood as data associated with the intraluminal image of the target vessel. For example, it can include at least one of the transverse and longitudinal sections of the intraluminal image, the vessel contour, the index identifier, the side branch identifier, the registration identifier, and the vessel diameter, as exemplified above. Of course, it can also include other data related to the intraluminal image. On this basis, it should be emphasized that the intraluminal image data in the embodiments of the present application at least includes the index identifier.

[0054] In the intracavitary image area, intracavitary image data is displayed.

[0055] S130. In response to a movement operation on the displayed first index mark or the second index mark, the moved first index mark is displayed in the angiography image region and the moved second index mark is displayed in the intracavitary image region.

[0056] In some embodiments, when the first index marker and the second index marker are displayed, a move operation is received. The move operation can be understood as an operation input for moving the first index marker, or an operation input for moving the second index marker. In actual applications, the operation can be, for example, a click operation or a drag operation input via a mouse, or an up operation, down operation, left operation, or right operation input via a keyboard. In actual applications, it can be understood that, for a cross-section displayed in the intracavitary image cross-section area, a frame change operation on the cross-section is a move operation for moving the index marker.

[0057] According to the above explanation, it can be known that the index identifier is used to identify the index position, such as the first index identifier is used to identify the index position in the angiographic image, and the second index identifier is used to identify the index position in the intracavitary image. On this basis, when the registration between the angiographic image and the intracavitary image is completed, taking the moving operation for the first index identifier as an example, the movement of the first index identifier means the movement of the index position in the angiographic image. At this time, the index position in the intracavitary image is no longer the original position, but a position that matches the index position after the movement in the angiographic image. Then, the second index identifier used to identify the index position in the intracavitary image will also move accordingly. The above analysis logic is also applicable to the moving operation for the second index identifier.

[0058] Therefore, after receiving the move operation, the first index marker after the move can be displayed in the angiographic image area and the second index marker after the move can be displayed in the intracavitary image area in response to the move operation. For example, taking the example shown in FIG1a as an example, after the index marker in any of the six areas is moved, the index markers in the remaining five areas will also move accordingly. Therefore, the moved index marker can be displayed in each area separately, so that the user can intuitively understand the registration effect between the two images.

[0059] The technical solution of the embodiment of the present application is for the angiographic image area and the intraluminal image area set on the registration interactive interface, by displaying the angiographic image data of the target blood vessel in the angiographic image area, and displaying the intraluminal image data of the target blood vessel in the intraluminal image area, the angiographic image data and the intraluminal image data both include at least an index mark for marking the index position of the target blood vessel; on this basis, in response to the movement operation of the displayed first index mark or the second index mark, the moved first index mark is displayed in the angiographic image area and the moved second index mark is displayed in the intraluminal image area. In the above technical solution, after moving the index mark in either the angiographic image area or the intraluminal image area, the index mark in the other area will also move and be displayed accordingly, which allows the user to intuitively perceive the registration effect between the angiographic image and the intraluminal image, thereby effectively improving the user experience.

[0060] An optional technical solution, the above-mentioned interactive method for registration of angiography and intracavitary images, further includes:

[0061] Acquire an angiographic image and an intracavitary image of a target blood vessel, as well as a selected registration segment of the target blood vessel presented by the angiographic image;

[0062] In the angiography image, the blood vessel contour of the registration segment is segmented, and the angiography image and the intracavitary image are registered based on the blood vessel contour and the registration segment.

[0063] For example, for the target blood vessel, the user imports the angiography image and selects the blood vessel segment of interest in the angiography image (i.e., the registration segment). At this time, the background registration algorithm can segment out the blood vessel contour of the registration segment, for example, it can be the contour of the main branch of the blood vessel in the registration segment; in addition, the user imports the intracavitary image to be registered with the angiography image. At this time, the background registration algorithm can realize the registration between the angiography image and the intracavitary image according to the blood vessel contour, that is, find the blood vessel segment corresponding to the registration segment in the intracavitary image.

[0064] The above technical solution realizes the effective registration between the angiographic image and the intracavitary image.

[0065] FIG3 is a flowchart of another method for interactive registration of angiography and intracavitary images provided in an embodiment of the present application. This embodiment is modified based on the above-mentioned technical solutions. In this embodiment, optionally, for the registration segment in the target blood vessel, in response to a movement operation on the displayed first index mark or the second index mark, the moved first index mark is displayed in the angiography image area and the moved second index mark is displayed in the intracavitary image area, including: in response to the movement operation on the displayed first index mark, when the index position corresponding to the moved first index mark is within the registration segment, the moved first index mark is displayed in the angiography image area and the moved second index mark is displayed in the intracavitary image area; or, in response to the movement operation on the displayed second index mark, when the index position corresponding to the moved second index mark is within the registration segment, the moved first index mark is displayed in the angiography image area and the moved second index mark is displayed in the intracavitary image area. The explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0066] Referring to FIG3 , the method of this embodiment may include the following steps:

[0067] S210. Display the angiographic image data of the target blood vessel in the angiographic image area on the registration interaction interface, wherein the angiographic image data at least includes a first index mark that marks an index position of the target blood vessel.

[0068] S220. Display the intracavity image data of the target blood vessel in the intracavity image area on the registration interaction interface, wherein the intracavity image data at least includes a second index mark marking the index position.

[0069] S230. In response to a movement operation on the displayed first index marker, when the index position corresponding to the moved first index marker is within the registration segment in the target blood vessel, the moved first index marker is displayed in the angiography image area and the moved second index marker is displayed in the intracavitary image area.

[0070] In some embodiments, since the registration segment is a vascular segment that has been registered between the angiography image and the intracavitary image, for the case where the moving operation is for the first index marker, if the index position corresponding to the moved first index marker is within the registration segment, this means that an index position that matches the moved index position in the angiography image can be found in the intracavitary image, and further means that the moved second index marker can be determined. Therefore, the moved first index marker can be displayed in the angiography image area and the moved second index marker can be displayed in the intracavitary image area.

[0071] For example, taking the example shown in Figure 1a as an example, the first index marker in any area of ​​the movable angiography image display area, the angiography image branch map area and the angiography image blood vessel diameter map area, when the index position corresponding to the moved first index marker is within the registration segment, the corresponding moved index marker can be displayed in each of the six areas.

[0072] S240. In response to a movement operation on the displayed second index marker, when the index position corresponding to the moved second index marker is within the registration segment, the moved first index marker is displayed in the angiographic image area and the moved second index marker is displayed in the intracavitary image area.

[0073] When the move operation is for the second index identifier, the display logic of the index identifier is similar to the above steps.

[0074] It should be noted that the above S230 and S240 can be selectively executed according to the target object of the received move operation (ie, the first index identifier or the second index identifier).

[0075] The technical solution of the embodiment of the present application is that when the index position corresponding to the moved index marker in a certain area is within the alignment segment, this indicates that a matching index position can be found in another area. Therefore, the moved index marker can be displayed in each area respectively, thereby achieving accurate display of the index marker.

[0076] In an optional technical solution, after responding to a movement operation on the displayed first index mark, the above-mentioned angiography and intracavitary image registration interactive method further includes:

[0077] When the index position corresponding to the moved first index marker exceeds the registration segment, the moved first index marker is displayed in the angiographic image region and the second index marker is stopped from being displayed in the intracavitary image region.

[0078] In some embodiments, since the angiography image and the intracavitary image are not aligned with respect to the vascular segments in the target blood vessel other than the alignment segment, when the index position corresponding to the moved first index marker exceeds the alignment segment, this indicates that a matching index position cannot be found in the intracavitary image. Therefore, the moved first index marker can be displayed in the angiography image area and the second index marker can stop being displayed in the intracavitary image area.

[0079] Exemplarily, taking the example shown in Figure 1a as an example, the first index marker in any area of ​​the movable angiography image display area, the angiography image branch map area and the angiography image blood vessel diameter map area, when the index position corresponding to the moved first index marker exceeds the registration segment, the moved first index marker can be displayed in the angiography image display area, the angiography image branch map area and the angiography image blood vessel diameter map area respectively, and the second index marker can be stopped from being displayed in the intraluminal image cross-section area, the intraluminal image longitudinal section area and the intraluminal image blood vessel diameter map area. Exemplarily, a black screen can be displayed in the intraluminal image cross-section area, and the second index marker can be lost in the intraluminal image longitudinal section area and the intraluminal image blood vessel diameter map area, so that the user knows that the moved index position has not been registered.

[0080] The above technical solution can effectively ensure the accuracy of the displayed index identifiers.

[0081] On this basis, optionally, the intraluminal image region includes at least an intraluminal image cross-section region, and the second index marker displayed in the intraluminal image cross-section region is represented by a cross-section of the intraluminal image of the target blood vessel corresponding to the index position;

[0082] Displaying the moved first index mark in the angiographic image region and stopping displaying the second index mark in the intracavitary image region includes:

[0083] The moved first index mark is displayed in the angiographic image region and any cross section of the intracavitary image is stopped from being displayed in the intracavitary image cross section region.

[0084] In some embodiments, when the index position corresponding to the moved first index marker exceeds the registration segment, since an index position matching the moved index position cannot be found in the intracavitary image, that is, a cross-section corresponding to the moved index position cannot be found from all cross-sections of the intracavitary image, any cross-section can be stopped from being displayed in the cross-section area of ​​the intracavitary image, thereby achieving the effect of stopping displaying the second index marker.

[0085] Another optional technical solution, after responding to the movement operation on the displayed second index mark, the above-mentioned angiography and intracavitary image registration interactive method further includes:

[0086] When the index position corresponding to the moved second index marker exceeds the registration segment, the moved second index marker is displayed in the intracavitary image region and the first index marker is stopped from being displayed in the angiography image region.

[0087] For example, taking the example shown in Figure 1a as an example, the second index marker in any area of ​​the intraluminal image cross-section area, the intraluminal image longitudinal section area and the intraluminal image blood vessel diameter map area is moved. When the index position corresponding to the moved second index marker exceeds the registration segment, the moved second index marker can be displayed in the intraluminal image cross-section area, the intraluminal image longitudinal section area and the intraluminal image blood vessel diameter map area, respectively, and the first index marker is stopped from being displayed in the angiography image display area, the angiography image branch map area and the angiography image blood vessel diameter map area.

[0088] The above technical solution can effectively ensure the accuracy of the displayed index identifiers.

[0089] FIG4 is a flow chart of another angiography and intracavitary image registration interaction method provided in an embodiment of the present application. This embodiment is modified based on the above-mentioned technical solutions. In this embodiment, optionally, the angiography image data also includes a first registration mark for marking the registration position of the registration segment in the target blood vessel in the target blood vessel, and the intracavitary image data also includes a second registration mark for marking the registration position; the above-mentioned angiography and intracavitary image registration interaction method also includes: in response to a movement operation on the displayed first registration mark or the second registration mark, the moved first registration mark is displayed in the angiography image area and the moved second registration mark is displayed in the intracavitary image area. Among them, the explanations of the terms that are the same as or corresponding to the above-mentioned embodiments are not repeated here.

[0090] Referring to FIG4 , the method of this embodiment may include the following steps:

[0091] S310. Display the angiographic image data of the target blood vessel in the angiographic image area on the registration interaction interface, wherein the angiographic image data may include a first index identifier marking the index position of the target blood vessel and a first registration identifier marking the registration position of the registration segment in the target blood vessel in the target blood vessel.

[0092] In some embodiments, in the angiographic image, the first registration marker can be understood as an identifier used to describe the registration position of the registration segment in the target blood vessel. In addition to the first index marker, the angiographic image data also includes at least the first registration marker. The first registration marker is displayed in the angiographic image area.

[0093] S320. Display the intracavity image data of the target blood vessel in the intracavity image area on the registration interaction interface, wherein the intracavity image data at least includes a second index mark marking the index position and a second registration mark marking the registration position.

[0094] In some embodiments, in the intracavitary image, the second registration marker can be understood as an identifier used to describe the registration position of the registration segment in the target vessel. In addition to the second index marker, the intracavitary image data also includes at least the second registration marker. The second registration marker is displayed in the intracavitary image area.

[0095] S330. In response to a movement operation on the displayed first index mark or the second index mark, display the moved first index mark in the angiography image region and display the moved second index mark in the intracavitary image region.

[0096] S340. In response to a movement operation on the displayed first registration marker or the second registration marker, display the moved first registration marker in the angiography image region and display the moved second registration marker in the intracavitary image region.

[0097] In some embodiments, when the first registration mark and the second registration mark are displayed, a moving operation is received. The moving operation can be understood as an operation input for the first registration mark for moving the first registration mark, or an operation input for the second registration mark for moving the second registration mark. In actual applications, it can be, for example, a click operation or a drag operation input through a mouse, or an up operation, down operation, left operation or right operation input through a keyboard.

[0098] According to the above explanation, it can be known that the registration mark is used to identify the registration position, such as the first registration mark is used to identify the registration position in the angiographic image, and the second registration mark is used to identify the registration position in the intracavitary image. On this basis, here we take the moving operation as an example for the first registration mark. The movement of the first registration mark means the change of the registration position (or registration segment) in the angiographic image. At this time, the background registration algorithm can re-register the angiographic image and the intracavitary image for the changed registration segment, thereby obtaining the registration position (or registration segment) in the intracavitary image, and then obtaining the second registration mark used to identify the registration position. In other words, compared with the previous second registration mark, the current second registration mark has moved. The above analysis logic is also applicable to the moving operation on the second registration mark.

[0099] Therefore, after receiving the move operation, the first registration marker after the move can be displayed in the angiographic image area and the second registration marker after the move can be displayed in the intracavitary image area in response to the move operation. For example, taking the example shown in FIG1a as an example, the registration segment can be changed by moving the second registration markers on both sides of the registration segment in the longitudinal section area of ​​the intracavitary image, and then the moved registration markers are displayed in each of the six areas, so that the user can intuitively know the registration segments in the angiographic image and the intracavitary image.

[0104] Figure 5 is a flow chart of another angiography and intracavitary image registration interaction method provided by an embodiment of the present application. This embodiment is modified based on the above-mentioned technical solutions. In this embodiment, optionally, the above-mentioned angiography and intracavitary image registration interaction method also includes: displaying a manual registration control on the registration interaction interface; setting the registration mode to the manual registration mode in response to the trigger operation for the manual registration control; in the manual registration mode, in response to the movement operation for the displayed first index identifier and the second index identifier, the angiography image and the intracavitary image of the target blood vessel are registered according to the index position corresponding to the moved first index identifier and the index position corresponding to the moved second index identifier; the moved first index identifier is displayed in the angiography image area and the moved second index identifier is displayed in the intracavitary image area. Among them, the explanations of the terms that are the same as or corresponding to the above-mentioned embodiments are not repeated here.

[0105] Referring to FIG5 , the method of this embodiment may include the following steps:

[0106] S410. Display the angiographic image data of the target blood vessel in the angiographic image area on the registration interaction interface, wherein the angiographic image data at least includes a first index mark that marks an index position of the target blood vessel.

[0107] S420. Display the intracavity image data of the target blood vessel in the intracavity image area on the registration interaction interface, wherein the intracavity image data at least includes a second index mark marking the index position.

[0108] S430. In response to a movement operation on the displayed first index mark or the second index mark, the moved first index mark is displayed in the angiography image region and the moved second index mark is displayed in the intracavitary image region.

[0109] S440. Display manual registration controls on the registration interactive interface.

[0110] In some embodiments, the manual registration control can be understood as a control that, when triggered, enables manual registration. In practical applications, the manual registration control can optionally be represented in various forms, such as a button, an option, or an input box. The manual registration control is displayed on the registration interaction interface.

[0111] S450. In response to a triggering operation on the manual registration control, set the registration mode to the manual registration mode.

[0112] In some embodiments, the trigger operation can be understood as an operation for triggering the manual registration control. After receiving the trigger operation, the registration mode can be set to the manual registration mode in response to the trigger operation, for example, the registration mode can be switched from the default automatic registration mode to the manual registration mode.

[0113] S460. In manual registration mode, in response to the movement operation of the displayed first index marker and the second index marker, the angiographic image and the intracavitary image of the target blood vessel are registered according to the index position corresponding to the moved first index marker and the index position corresponding to the moved second index marker.

[0114] In some embodiments, a move operation can be understood as an operation inputted for moving the first and second registration marks displayed in manual registration mode. Understood from another perspective, a move operation can include a first move operation and a second move operation, wherein the first move operation can be understood as an operation inputted for moving the first registration mark displayed in manual registration mode; and the second move operation can be understood as an operation inputted for moving the second registration mark displayed in manual registration mode.

[0115] In response to the moving operation, the index position in the angiographic image corresponding to the first index marker after the move and the index position in the intracavitary image corresponding to the second index marker after the move can be determined. At this time, the background registration algorithm can re-register the angiographic image and the intracavitary image based on the two index positions.

[0116] For example, taking the example shown in Figure 1a as an example, the first index mark in any area of ​​the movable angiography image display area, the angiography image branch map area and the angiography image blood vessel diameter map area, as well as the second index mark in any area of ​​the intraluminal image cross-section area, the intraluminal image longitudinal section area and the intraluminal image blood vessel diameter map area, select the appropriate alignment point, confirm, and thus complete the manual alignment.

[0117] S470. Display the moved first index mark in the angiography image region and display the moved second index mark in the intracavitary image region.

[0118] The technical solution of the embodiment of the present application, in manual registration mode, changes the index position in the radiographic image and the index position in the intracavitary image by moving two index markers, thereby realigning the image according to the two changed index positions, thereby achieving the effect of manual registration.

[0122] When the pixel points corresponding to the first stenosis marker and the second stenosis marker are not registration points, first information is displayed in a first window on the registration interaction interface, wherein the first information is used to prompt confirmation of whether the registration result between the angiographic image of the target blood vessel and the intracavitary image is correct.

[0123] In some embodiments, in angiographic images, the first stenosis marker can be understood as a marker used to mark a stenosis in a target blood vessel. In addition to the first index marker, the angiographic image data also includes at least the first stenosis marker. The first stenosis marker is displayed in the vessel diameter map area of ​​the angiographic image. In practical applications, the first stenosis marker can optionally be obtained by analyzing the stenosis presented in the angiographic image.

[0124] In intraluminal images, the second stenosis marker can be understood as a marker used to mark a stenosis. In addition to the second index marker, the intraluminal image data also includes at least the second stenosis marker. The second stenosis marker is displayed in the intraluminal image vessel diameter map area. In practical applications, the second stenosis marker can optionally be obtained by analyzing the stenosis displayed in the intraluminal image.

[0125] When the registration between the angiographic image and the intracavitary image is completed, if the pixel points corresponding to the two stenosis markers are not the registration points, this indicates that there may be deviations in the registration result at this time. In this case, the first message prompting the user to confirm whether the registration result is correct can be displayed in the first window on the registration interaction interface.

[0126] The above technical solution realizes the automatic judgment of the correctness of the registration result and automatically prompts the user when there may be errors, thereby achieving the effect of correcting erroneous registration results in a timely manner.

[0130] When the pixel points corresponding to the first side branch identifier and the second side branch identifier are not registration points, the second information is displayed in the second window on the registration interaction interface, wherein the second information is used to prompt confirmation of whether the registration result between the angiographic image of the target blood vessel and the intracavitary image is correct.

[0131] In some embodiments, in an angiographic image, the first side branch identifier can be understood as an identifier used to mark the location of a side branch in the target vessel. In addition to the first index identifier, the angiographic image data also includes at least the first side branch identifier. The first side branch identifier is displayed in the angiographic image branch map area. In practical applications, the first side branch identifier can optionally be obtained by analyzing the vessel side branches presented in the angiographic image.

[0132] In intracavitary images, the second side branch identifier can be understood as an identifier used to mark the location of a side branch. In addition to the second index identifier, the intracavitary image data also includes at least the second side branch identifier. The second side branch identifier is displayed in the longitudinal section of the intracavitary image. In practical applications, the second side branch identifier can optionally be obtained by analyzing the vascular side branches displayed in the intracavitary image.

[0133] When the registration between the angiographic image and the intracavitary image is completed, if the pixel points corresponding to the two side branch markers are not the registration points, this indicates that there may be deviations in the registration result at this time. In this case, a second message can be displayed in the second window on the registration interaction interface to prompt the user to confirm whether the registration result is correct.

[0134] The above technical solution realizes the automatic judgment of the correctness of the registration result and automatically prompts the user when there may be errors, thereby achieving the effect of correcting erroneous registration results in a timely manner.
