[0026] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended to be merely illustrative of the present application and not in limitation thereof. It should also be noted that, for the purpose of description, only the parts related to the present application are shown in the accompanying drawings rather than all the parts.

[0027] Figure 1 Fig. 1 is a structural schematic diagram of a computer device according to an embodiment of the present application.

[0028] As shown in Fig. 1, the computer device according to the present embodiment includes a blood vessel image display method. Figure 1 The blood vessel image display method according to the present embodiment includes the following steps.

[0029] S110, in response to a click operation in a display window of a first blood vessel image slice of the three-dimensional blood vessel image data, determining a click position coordinate of the click operation.

[0030] The three-dimensional blood vessel image data can be an angiography image or a magnetic resonance angiography image. The format of the three-dimensional blood vessel image data can be any one of a Nearly Raw Raster Data (NRRD,.nrrd), a segmented / segmented NRRD format (.seg.nrrd), or a Neuroimaging Informatics Technology Initiative (NIfTI format,.nii.gz).

[0031] The first blood vessel image slice can be an image slice of the three-dimensional blood vessel image data in any one of three orthogonal planes of a three-dimensional image space coordinate system. The three-dimensional image space coordinate system can include X, Y, and Z directions, and the three orthogonal planes can be XY, XZ, and YZ planes. It can be understood that in a blood vessel image slice corresponding to the XY plane, the z value of the pixel points is the same; in a blood vessel image slice corresponding to the XZ plane, the y value of the pixel points is the same; and in a blood vessel image slice corresponding to the YZ plane, the x value of the pixel points is the same.

[0032] The first blood vessel image slice in the display window can be one blood vessel image slice corresponding to an arbitrary z value in the three-dimensional blood vessel image data range in one blood vessel image slice corresponding to the XY plane; or one blood vessel image slice corresponding to an arbitrary y value in the three-dimensional blood vessel image data range in one blood vessel image slice corresponding to the XZ plane; or one blood vessel image slice corresponding to an arbitrary x value in the three-dimensional blood vessel image data range in one blood vessel image slice corresponding to the YZ plane.

[0033] The clicking operation can be an interactive operation of a moving cursor of a mouse with the display window, a touch operation in a touch screen, or an interactive operation corresponding to a remote control signal sent by a remote controller. The clicking position coordinates corresponding to the clicking operation are screen coordinates in the blood vessel image slice display window.

[0034] In an optional embodiment, a user can select one three-dimensional blood vessel image data to be displayed in an image display interface, and the image display interface can synchronously display blood vessel image slices in slice directions corresponding to three orthogonal planes. For example, a blood vessel three-dimensional structure corresponding to a set of three-dimensional blood vessel image data can be a three-dimensional blood vessel structure as shown in the figure. Figure 2 The first blood vessel image slice can be any one image slice in the three display windows. Figure 3

[0035] Specifically, Figure 3 In the figure (a), the image is a blood vessel image slice corresponding to the XY orthogonal plane with z = 60; Figure 3 In the figure (b), the image is a blood vessel image slice corresponding to the XZ orthogonal plane with y = 333; Figure 3 In the figure (c), the image is a blood vessel image slice corresponding to the YZ orthogonal plane with x = 256. The coordinate information, name, and the like of the blood vessel image slice are displayed on each display window. In addition, more image interactive function controls, such as zoom in, zoom out, flip, contour cutout, and at least one of other image processing function controls, can be displayed in the corresponding image display interface. Figure 3

[0036] S120, according to the clicking position coordinates, generating and displaying a gradual color blood vessel depth map corresponding to all blood vessel image slices above and below the first blood vessel image slice in the slice direction.

[0037] The clicking position coordinates are screen coordinates, which can be converted into coordinates corresponding to the three-dimensional blood vessel image data according to the mapping relationship between the screen coordinate system and the three-dimensional image space coordinate system.

[0038] ​​In the embodiment, the first blood vessel image slice is a depth information reference plane. The depth information of the blood vessels in each of the adjacent blood vessel image slices above and below the first blood vessel image slice is determined.

[0039] In an alternative embodiment, first, the relative distance between each of the blood vessel image slices above and below the first blood vessel image slice and the first blood vessel image slice can be calculated. Specifically, the total number of image slices in the slice direction corresponding to each orthogonal plane can be determined according to the data dimension of the three-dimensional blood vessel image data. The relative distance between each of the blood vessel image slices above and below the first blood vessel image slice and the first blood vessel image slice can be determined according to the distance normalization based on the total number of image slices.

[0040] Further, the first color is selected from a preset gradual color palette based on the relative distance. The color filling region in the associated blood vessel image slice is filled with the first color to obtain a depth blood vessel image slice. The color filling region can be a pixel region in the blood vessel image slice including the corresponding blood vessel. Finally, the corresponding depth blood vessel image slices of the blood vessel image slices above and below the first blood vessel image slice are spliced and displayed. The image display effect can be that the distance from the first blood vessel image is from small to large, and the corresponding blood vessel color can be from deep to shallow or from shallow to deep.

[0041] In an alternative embodiment, the color filling region can be the region after removing the corresponding blood vessel contour from the blood vessel region in each blood vessel image slice.

[0042] The determination process of the blood vessel contour includes the following steps:

[0043] First, a corresponding binary mask image is created for each blood vessel image slice, in which the blood vessel contour can be represented by black color to highlight the blood vessel edge.

[0044] Second, the binary mask image is eroded to obtain an eroded mask image, so as to reduce the blood vessel region.

[0045] Third, the binary mask image is subtracted from the eroded mask image to obtain the blood vessel contour. That is, the original mask - the eroded mask = the contour (corresponding to the edge part).

[0046] Through the above three steps, a black contour (edge) can be generated for the blood vessel region, enhancing the boundary display of the blood vessels in the depth map and making the structure clearer.

[0047] In yet another optional embodiment, the preset gradient color palette is a rainbow color palette, and the mapping relationship has the gradient from red to purple corresponding to the distance from small to large. That is, in the upper and lower full sets of blood vessel image slices, the blood vessel region in the image slice closest to the first blood vessel image slice is represented by red, and the blood vessel region in the image slice farthest from the first blood vessel image slice is represented by purple.

[0048] The display effect of the gradient color blood vessel depth map can refer to the results shown in Figure 4 In the image display interface, two sub-image display windows associated with the first blood vessel image slice (the display window corresponding to the first blood vessel image slice) are created; and the gradient color blood vessel depth maps corresponding to the upper and lower full sets of blood vessel image slices are displayed in the sub-image display windows, respectively.

[0049] In a specific embodiment, the process of obtaining Figure 4 The process of obtaining the gradient color blood vessel depth map in

[0050] First, a rainbow color spectrum with a gradient from red to orange to yellow to green to cyan to blue to purple can be created in advance, and each color in the spectrum is in RGBA format, including four color channels (4 channels: R, G, B, Alpha transparency), wherein the value of the last channel represents the transparency. An RGBA canvas (4 channels: R, G, B, Alpha transparency) is also created, and the initial value of the transparency can be black.

[0051] Then, the total number of layers Z in the slice dimension of the first blood vessel image slice is determined according to the dimensions of the three-dimensional blood vessel image data, for normalization of the distance. Assuming that the number of layers corresponding to the first blood vessel image slice is z1, and any other blood vessel image slice is at layer z0. Then, the normalized result of the relative distance of each blood vessel image slice to the first blood vessel image slice can be represented as the absolute value of the result of z0-z1 divided by the total number of layers Z. Further, the color can be obtained in the rainbow color spectrum according to the calculated ratio. The closer the ratio is to 0, the closer the color is to red, and the closer the ratio is to 1, the closer the color is to purple. Before obtaining the color, it can also be determined whether there is blood vessel data in each blood vessel image slice. If not, the corresponding blood vessel image slice can be skipped and not processed.

[0052] Further, the transparency of the color corresponding to each blood vessel image slice can be set, for example, to 30%. Then, the rainbow color and transparency corresponding to each blood vessel image slice are superimposed, and the gradient color blood vessel depth maps corresponding to the upper and lower full sets of blood vessel image slices are obtained.

[0053] In addition, the transparency corresponding to the blood vessel contour can be further adjusted, for example, a color layer with 30% transparency is superimposed on each layer image slice in the depth order to realize the blood vessel edge enhancement. Thus, the obtained blood vessel depth image can distinguish different layer image slices, overcome the defect of blurred structure boundary in the traditional layered display, and realize the transparent superposition with contour enhancement. The technical scheme of the embodiment, in response to the click operation in the display window of the first blood vessel image slice of the three-dimensional blood vessel image data, determines the click position coordinates of the click operation; according to the click position coordinates, the gradient color blood vessel depth image corresponding to all the blood vessel image slices above and all the blood vessel image slices below adjacent to the first blood vessel image slice in the slice direction is generated and displayed. The technical scheme of the embodiment solves the problems of poor blood vessel image visualization effect, inability to highlight the depth information, and unclear slice boundary, can make the blood vessel image have stronger depth perception in vision, distinguish different image slices with different colors, and make the image boundary more clear.

[0054] Figure 5 The flowchart of the blood vessel image display method provided by the embodiment of the application, the blood vessel image display method in the embodiment and the above-mentioned embodiments belong to the same inventive concept, and further describes the process of sliding switching the first blood vessel image slice and displaying the blood vessel depth information. The method can be executed by a blood vessel image display device, and the device can be realized by software and / or hardware and integrated in a computer device with application development function.

[0055] As shown in Figure 5 , the blood vessel image display method of the embodiment includes the following steps:

[0056] S210, in response to the sliding operation in the display window of the first blood vessel image slice of the three-dimensional blood vessel image data, switching the blood vessel image slice in the display window according to the sliding direction and the sliding distance of the sliding operation.

[0057] The first blood vessel image slice can be any one of the blood vessel image slices of the first three-dimensional blood vessel image data in the three orthogonal planes of the three-dimensional image space coordinate system. The switched blood vessel image slice is other blood vessel image slice of the first blood vessel image slice in the corresponding slice direction of the three-dimensional image space coordinate system. In one specific example, the display process of the first blood vessel image slice can include the following steps:

[0058] First, the first three-dimensional blood vessel image data is obtained, which can be represented as a three-dimensional array (x, y, z). After loading the first three-dimensional blood vessel image data, the initialization display can be performed according to the dimension size of the three-dimensional array, which can be as Figure 3The three-view gray scale display of the blood vessel image (the blood vessel is white and the background is black) is performed as shown in the middle of the figure, and the initial slice position can be the slice corresponding to the midpoint (x / 2, y / 2, z / 2) of each axis in the three-dimensional image space coordinate system.

[0059] In the process of image display, the image data corresponding to the first blood vessel image slice in the first three-dimensional blood vessel image data is acquired, and the image data corresponding to the first blood vessel image slice can also be subjected to a nearby difference value calculation to maintain the sharpness of the image. Further, the image data corresponding to the first blood vessel image slice is subjected to gray scale display and the position information corresponding to the first blood vessel image slice is displayed; wherein the position information can be displayed as the title of the first blood vessel image slice. The display effect of the gray scale display is that the blood vessel is displayed as white and the background area other than the blood vessel is displayed as black.

[0060] The sliding operation in the display window can be a mouse sliding or a gesture sliding. If the sliding operation is the first blood vessel image slice corresponding to the XY view, the Z-axis slice is adjusted; if the sliding operation is the first blood vessel image slice corresponding to the XZ view, the Y-axis slice is adjusted; if the sliding operation is the first blood vessel image slice corresponding to the YZ view, the X-axis slice is adjusted. The target blood vessel image slice of switching can be determined according to the distance and direction of the sliding, and the corresponding display window is refreshed according to the image data corresponding to the target blood vessel image slice.

[0061] S220, in response to the click operation in the display window for the switched first blood vessel image slice, determining the click position coordinates of the click operation.

[0062] S230, according to the click position coordinates, generating and displaying the gradient color blood vessel depth map corresponding to all the blood vessel image slices above and below the adjacent slice direction of the switched first blood vessel image slice.

[0063] The process of determining the corresponding gradient color blood vessel depth map by clicking the switched first blood vessel image slice can refer to the process described in the above embodiments. The difference is that the position of the slice corresponding to the first blood vessel image slice is different. Through this embodiment, the interactive response speed can be optimized to realize real-time slice position tracking and depth map generation.

[0064] The technical scheme of the embodiment is: in response to a sliding operation in a display window of a first blood vessel image slice of three-dimensional blood vessel image data, switching the blood vessel image slice in the display window according to a sliding direction and a sliding distance of the sliding operation; in response to a click operation in the display window for the switched first blood vessel image slice, determining a click position coordinate of the click operation; and generating and displaying a gradient color blood vessel depth map corresponding to all blood vessel image slices above and all blood vessel image slices below adjacent to the switched first blood vessel image slice in the slice direction according to the click position coordinate. The technical scheme of the embodiment can solve the problems of poor blood vessel image visualization effect, inability to highlight depth information, and unclear slice boundary, can make the blood vessel image have stronger visual depth perception, and can distinguish different image slices by using different colors and make the image boundary clearer.
