[0026] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0027] Figure 1 This is a flowchart of a method for displaying vascular images, provided in an embodiment of the present invention. This embodiment is applicable to scenarios involving vascular image visualization, particularly those requiring the display of vascular depth information. This method can be performed by a vascular image display device, which can be implemented using software and / or hardware and integrated into a computer device with application development capabilities, such as a medical image processing system.

[0028] like Figure 1 As shown, the blood vessel image display method of this embodiment includes the following steps:

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

[0030] The 3D vascular image data may be an angiography image or a magnetic resonance angiography image. The 3D vascular image data may be in a text-based medical image format (Nearly Raw Raster Data, .nrrd), a segmented / segmented NRRD format (.seg.nrrd), or a standard format in the field of neuroimaging (Neuroimaging Informatics Technology Initiative, NIfTI format, .nii.gz).

[0031] The first vascular image slice can be an image slice of the three-dimensional vascular image data in any one of three orthogonal planes in a three-dimensional image space coordinate system. The three-dimensional image space coordinate system can be a spatial coordinate system including the X, Y, and Z directions, and the corresponding three orthogonal planes can be the XY, XZ, and YZ planes. It is understood that in a vascular image slice corresponding to the XY plane, the z values ​​of the pixels are the same; in a vascular image slice corresponding to the XZ plane, the y values ​​of the pixels are the same; and in a vascular image slice corresponding to the YZ plane, the x values ​​of the pixels are the same.

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

[0033] The click operation can be an interaction between the mouse cursor and the display window, a touch operation on a touch screen, or an interaction corresponding to a remote control signal from a remote controller. The click position coordinates corresponding to the click operation are the screen coordinates in the vascular image slice display window.

[0034] In an optional embodiment, the user can select a 3D blood vessel image data to display in the image display interface, and the image display interface can simultaneously display the blood vessel image slices in the slice directions corresponding to three orthogonal planes. For example, the 3D blood vessel structure corresponding to a set of 3D blood vessel image data can be Figure 2 The first blood vessel image slice can be Figure 3 Any image slice in the three display windows.

[0035] Specifically, Figure 3 The image in (a) is a blood vessel image slice corresponding to the XY orthogonal plane corresponding to z=60; Figure 3 The image in (b) is a blood vessel image slice corresponding to the XZ orthogonal plane corresponding to y=333; Figure 3 The image (c) is a slice of the vascular image corresponding to the YZ orthogonal plane corresponding to x=256. Each display window shows the coordinate information, name, etc. of the vascular image slice. In addition, you can also Figure 3 The corresponding image display interface displays more image interactive function controls, such as at least one of zoom in, zoom out, flip, outline cutout, and other image processing function controls.

[0036] S120 , generating and displaying, based on the click position coordinates, a gradient blood vessel depth map corresponding to all upper blood vessel image slices and all lower blood vessel image slices adjacent in a slice direction to the first blood vessel image slice.

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

[0038] In this embodiment, the first blood vessel image slice is a depth information reference plane. The depth information of blood vessels in adjacent blood vessel image slices is determined upward and downward based on the first blood vessel image slice.

[0039] In an optional embodiment, the relative distance between each vessel image slice in all upper and lower vessel image slices and the first 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 based on the data dimensions of the three-dimensional vessel image data. Distance normalization can be performed based on the total number of image slices to determine the relative positional relationship, i.e., the relative distance, between each vessel image slice in all upper and lower vessel image slices and the first vessel image slice.

[0040] Then, based on the relative distance, a first color is selected from a preset gradient color palette that is mapped to the distance. The color-filled area in the associated vascular image slice is filled with the first color to obtain a depth vascular image slice. The color-filled area may be a pixel region within the vascular image slice that includes the corresponding vascular image. Finally, the depth vascular image slices corresponding to all upper and lower vascular image slices are spliced ​​and displayed. The resulting image display effect can be such that the corresponding vascular color changes from dark to light, or from light to dark, as the distance from the first vascular image increases.

[0041] In an optional implementation, the color-filled area may be an area obtained by removing the corresponding blood vessel contour from the blood vessel area in each blood vessel image slice.

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

[0043] In the first step, a corresponding binary mask image is created for each vascular image slice, wherein the vascular contour can be represented by black in the binary mask image to highlight the vascular edge.

[0044] In the second step, the binary mask image is eroded to obtain an eroded mask image to reduce the blood vessel area.

[0045] The third step is to subtract the eroded mask image from the binary mask image to obtain the vessel contour. That is, the original mask - the eroded mask = the contour (corresponding to the edge).

[0046] Through the above three steps, a black outline (edge) can be generated for the blood vessel area, which can enhance the boundary display of the blood vessels in the depth map and make the structure clearer.

[0047] In another alternative embodiment, the preset gradient color palette is a rainbow color palette, and in the mapping relationship, the color gradient from red to purple corresponds to increasing distance. That is, in all the upper and lower vascular image slices, the vascular region in the image slice closest to the first vascular image slice is represented by red, and the vascular region in the image slice farthest from the first vascular image slice is represented by purple.

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

[0049] In a specific embodiment, Figure 4 The process of the gradient color blood vessel depth map can refer to the following process:

[0050] First, you can create a rainbow color spectrum with a gradient of red, orange, yellow, green, cyan, blue, and violet. Each color in the spectrum is in RGBA format, consisting of four color channels (4 channels: R, G, B, and alpha transparency). The value corresponding to the last channel indicates the transparency. Then, create an RGBA canvas (4 channels: R, G, B, and alpha transparency). The initial transparency value can be completely black.

[0051] Next, the total number of layers Z in the slice dimension of the first vascular image slice is determined based on the dimensionality of the 3D vascular image data for distance normalization. Assume that the first vascular image slice corresponds to layer z1, and all other vascular image slices are at layer z0. Therefore, the normalized relative distance between each vascular image slice and the first vascular image slice can be expressed as the ratio of the absolute value of the result z0 - z1 to the total number of layers Z. Furthermore, a color can be selected from the rainbow color spectrum based on 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 selecting the color, it is also possible to determine whether each vascular image slice contains vascular data. If not, the corresponding vascular image slice can be skipped and not processed.

[0052] Furthermore, the transparency of the color corresponding to each vascular image slice can be set, for example, to 30%. Then, by overlaying the rainbow colors and transparency corresponding to each vascular image slice, a gradient vascular depth map corresponding to all the vascular image slices above and below can be obtained.

[0053] In addition, the transparency corresponding to the vascular contour can be further adjusted. For example, a color layer with 30% transparency is superimposed on each image slice in depth order to enhance the vascular edge. The resulting vascular depth image can thus distinguish between different layers of image slices, overcoming the defect of blurred structural boundaries in traditional layered display and achieving transparent superposition with contour enhancement. The technical solution of this embodiment determines the click position coordinates of the click operation in response to a click operation within the display window of the first vascular image slice of the three-dimensional vascular image data; based on the click position coordinates, a gradient vascular depth map corresponding to all adjacent vascular image slices above and all adjacent vascular image slices below in the slice direction corresponding to the first vascular image slice is generated and displayed. The technical solution of the embodiment of the present invention solves the problems of poor visualization of vascular images, inability to highlight depth information, and unclear slice boundaries. It can make the visual depth perception of vascular images stronger, distinguish different image slices with different colors, and make the image boundaries clearer.

[0054] Figure 5 This flowchart illustrates a method for displaying a vascular image according to an embodiment of the present invention. This embodiment shares the same inventive concept as the vascular image display method described above and further describes the process of sliding a first vascular image slice and displaying vascular depth information. This method can be performed by a vascular image display device, which can be implemented using software and / or hardware and integrated into a computer device with application development capabilities.

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

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

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

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

[0059] During image display, image data corresponding to a first vascular image slice in the first three-dimensional vascular image data is obtained. A near-interpretation difference calculation may also be performed on the image data corresponding to the first vascular image slice to maintain image sharpness. Furthermore, the image data corresponding to the first vascular image slice is displayed in grayscale, and position information corresponding to the first vascular image slice is displayed. The position information may be displayed as a title for the first vascular image slice. The grayscale display effect is that the blood vessels appear white, and the background area other than the blood vessels appears black.

[0060] Sliding within the display window can be done via mouse or gesture. If the slide operation is on the first vascular image slice corresponding to the XY view, the Z-axis slice is adjusted; if the slide operation is on the first vascular image slice corresponding to the XZ view, the Y-axis slice is adjusted; if the slide operation is on the first vascular image slice corresponding to the YZ view, the X-axis slice is adjusted. The target vascular image slice to be switched to is determined based on the sliding distance and direction, and the corresponding display window is refreshed based on the image data corresponding to the target vascular image slice.

[0061] S220 : In response to a click operation on the switched first blood vessel image slice in the presentation window, determine the click position coordinates of the click operation.

[0062] S230 , generating and displaying, based on the click position coordinates, a gradient blood vessel depth map corresponding to all upper blood vessel image slices and all lower blood vessel image slices adjacent in a slice direction to the switched first blood vessel image slice.

[0063] The process of clicking on the switched first vessel image slice to determine the corresponding gradient vessel depth map can be similar to the process described in the above embodiment. The difference lies in the different slice layer locations corresponding to the first vessel image slice. This embodiment optimizes interactive response speed and enables real-time slice position tracking and depth map generation.

[0064] The technical solution of this embodiment switches the displayed vascular image slices within the display window in response to a sliding operation within the display window of a first vascular image slice of three-dimensional vascular image data, based on the sliding direction and sliding distance of the sliding operation; determines the click position coordinates of the click operation in response to a click operation on the switched first vascular image slice within the display window; and generates and displays a gradient-colored vascular depth map corresponding to all vascular image slices above and below the switched first vascular image slice in the slice direction, based on the click position coordinates. The technical solution of this embodiment of the present invention solves the problems of poor vascular image visualization, the inability to highlight depth information, and unclear slice boundaries. It can enhance the visual depth perception of vascular images, distinguish different image slices with different colors, and make image boundaries clearer.

[0068] The technical solution of this embodiment responds to a click operation within the display window of a first vessel image slice of three-dimensional vessel image data by determining the click location coordinates. Based on the click location coordinates, a gradient-colored vessel depth map corresponding to all vessel image slices above and below the first vessel image slice in the slice direction corresponding to the first vessel image slice is generated and displayed.

[0078] The erosion mask image is subtracted from the binary mask image to obtain the blood vessel contour.

[0079] In an optional implementation, the preset gradient color palette is a rainbow color palette, and in the mapping relationship, distances from small to large correspond to a gradient of colors from red to purple.

[0084] In response to a sliding operation on the display window of the first blood vessel image slice, switching the display of the blood vessel image slice in the display window according to the sliding direction and sliding distance of the sliding operation;

[0085] The switched blood vessel image slices are other blood vessel image slices corresponding to the first blood vessel image slice in the slice direction of the three-dimensional image space coordinate system.

[0086] In an optional embodiment, the first blood vessel image slice is any one of the blood vessel image slices of the first three-dimensional blood vessel image data in three orthogonal planes of a three-dimensional image space coordinate system.
