[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] In the existing common technologies for examining gastrointestinal lesions by ultrasound instruments, most of them rely on niche imaging technology in a three-dimensional scene to observe the lesions, but the existing niche imaging can only observe the image of the selected position; or rely on multi-section imaging technology to observe the lesions, but multi-section imaging can only display parallel slice image information in one direction at a time, and cannot intuitively display the internal three-dimensional structure of the target image. To this end, the present application provides an ultrasonic multi-section niche imaging method, which can automatically combine the selected section image and the located section image into a niche image by selecting any section image after a multi-section imaging, and automatically positioning other section images according to the coordinates of the axis center point, so as to facilitate the user to observe the internal three-dimensional structure corresponding to any section image in the multi-section image.

[0063] See also Figure 1 As shown, an embodiment of the present invention discloses an ultrasonic multi-section niche imaging method, comprising:

[0064] Step S11 : determining a multi-slice image based on the three-dimensional ultrasound data, and selecting any slice image from the displayed multi-slice images as a first slice image of interest.

[0065] In this embodiment, Figure 2 As shown, the present application obtains three-dimensional ultrasound data of the detected tissue, determines the main section image from the three-dimensional ultrasound data, and configures the section parameters including the number of sections and the section distance, then clicks the multi-section imaging button in the tab of the ultrasound instrument display screen to enter the multi-section imaging function, and performs multi-section imaging on the three-dimensional ultrasound data by using a number of cutting guide lines for the position of interest determined based on the section parameters to obtain a multi-section image; then, any one section image is selected from the displayed multi-section images as the first section image of interest, and the niche imaging button in the tab of the ultrasound instrument display screen is clicked to enter the niche imaging function, and section images of interest of other dimensions are obtained from the three-dimensional ultrasound data based on the axis center point coordinates of the first section image of interest, thereby performing niche imaging on the first section image of interest and the section images of interest of other dimensions based on the axis center point coordinates to obtain a niche image of the stereoscopic structure corresponding to the first section image of interest.

[0066] Among them, for three-dimensional ultrasound data, the original ultrasound data of the detected tissue can be collected by its own ultrasound probe, and the original ultrasound data can be converted using a digital scan converter (DSC) to obtain three-dimensional ultrasound data; or the three-dimensional ultrasound data collected and transmitted by an external device can be directly obtained.

[0067] Furthermore, determining a multi-section image based on three-dimensional ultrasound data includes determining any single-dimensional main section image from the three-dimensional ultrasound data; and determining a number of parallel and equidistant cutting guide lines for the location of interest (including the lesion) on the main section image; performing multi-section imaging on the three-dimensional ultrasound data using the several cutting guide lines, so as to determine the multi-section image based on the section images corresponding to each cutting guide line. It should be noted that performing multi-section imaging on the three-dimensional ultrasound data using the several cutting guide lines can be based on extracting or calculating the section images corresponding to the several cutting guide lines from the three-dimensional ultrasound data, thereby determining the multi-section image. In addition, in some embodiments, the several cutting guide lines may also be guide lines that are non-parallel and / or non-equidistant.

[0068] Among them, determining a number of cutting guide lines for the position of interest on the main section image includes obtaining the number of sections and the distance of sections input by the user through the preset configuration text box in the current display screen to obtain the corresponding section parameters; or obtaining the number of sections and the distance of sections selected by the user through the preset configuration radio button in the current display screen to obtain the corresponding section parameters. After obtaining the section parameters including the number of sections and the distance of sections, by clicking the multi-section imaging button in the tab of the ultrasound instrument display screen, a number of cutting guide lines set in parallel and at equal distances corresponding to the position of interest (including the lesion) in the main section image are determined based on the section parameters including the number of sections and the distance of sections. It should be noted that after the user enters the number of slices and the slice distance for the first time through the preset configuration text box or the preset configuration radio button to perform multi-slice imaging of the three-dimensional ultrasound data, the user can also adjust the slice distance and / or the number of slices again through the preset configuration text box or the preset configuration radio button to re-perform multi-slice imaging of the three-dimensional ultrasound data according to the number of slices and the slice distance, thereby realizing the multi-slice imaging function of the three-dimensional ultrasound data multiple times when the three-dimensional ultrasound data is acquired only once, and avoiding the use of only a unified slice distance or a single slice distance for multi-slice imaging of the three-dimensional ultrasound data.

[0069] In a specific embodiment, any slice image is selected from the displayed multi-slice images as the first slice image of interest, including selecting any one cutting guide line from a number of cutting guide lines in the main slice image displayed on the current display screen as the target cutting guide line, and determining the target slice image corresponding to the target cutting guide line from the multi-slice images displayed on the current display screen as the first slice image of interest. The target cutting guide line can be selected by touch screen, such as a stylus, finger, etc., or by non-touch screen, such as a keyboard, mouse, etc. Specifically, the several cutting guide lines on the main slice image carry corresponding cutting guide line numbers, wherein the cutting guide line number is consistent with the slice number of the slice image corresponding to the cutting guide line. The target cutting guide line is selected from the several cutting guide lines, and the cutting guide line number corresponding to the target cutting guide line is used as the tangent line number of interest. The corresponding section length and section width are determined based on the number of image display frames currently on the display screen, and the offset address is determined based on the multiplication of the tangent line number of interest, the section length and the section width. The base address for storing multiple section images is determined from the memory, and the target storage address is determined based on the base address and the offset address, so as to use the target storage address to read the target section image corresponding to the target cutting guide line from the memory as the first section image of interest.

[0070] In another specific embodiment, selecting any slice image from the displayed multi-slice images as the first slice image of interest includes using a preset slice selection tool and obtaining the slice number of interest based on the displayed multi-slice images, and determining a target storage address based on the slice number of interest; and using the target storage address to read the corresponding slice image from the memory as the first slice image of interest. It can be understood that if Figure 3 As shown, the multi-slice images can be displayed on the current display screen in the form of thumbnails, and the thumbnails carry corresponding slice numbers for users to view and select; the user can click on the thumbnail corresponding to the multi-slice image displayed on the current display screen, or enter the slice number in the text box, so that the ultrasound instrument obtains the corresponding slice number of interest, and automatically calculates the offset address according to the slice number of interest, so as to determine the target storage address based on the offset address, and thus read the corresponding slice image from the memory through the target storage address as the first slice image of interest.

[0071] Step S12: Acquire the axis center point coordinates of the first section image of interest, and acquire a plurality of second section images of interest from the three-dimensional ultrasound data based on the axis center point coordinates.

[0072] In this embodiment, each slice image in the multi-slice image has two axes, namely, a horizontal axis and a vertical axis, and the intersection of the horizontal axis and the vertical axis is the axis center point of the slice image, and the horizontal axis and the vertical axis in the slice image are initially located at the corresponding preset default positions, and the axis center point is also initially located at the corresponding default position. Since the axis center point coordinates of each slice image in the multi-slice image have been calculated and saved in the memory during the multi-slice imaging of three-dimensional ultrasound data, after determining the first slice image of interest, if the current horizontal axis and the current vertical axis in the first slice image of interest are both located at the corresponding preset default positions, the axis center point coordinates of the first slice image of interest that have been saved in advance can be directly obtained from the memory.

[0073] It should be noted that, in order to facilitate the user to view the internal three-dimensional structure corresponding to any position in the selected first section image of interest, the user is allowed to adjust the center point of the axis in the first section image of interest. Specifically, the user can move the center point of the axis in the first section image of interest by dragging the center point of the axis in the first section image of interest on the current display screen, or adjust the horizontal axis and / or vertical axis in the first section image of interest on the current display screen, thereby adjusting the center point of the axis in the first section image of interest; wherein the user can adjust the center point of the axis by touch screen, for example, a stylus, a finger, etc.; or adjust the center point of the axis by non-touch screen, for example, by a peripheral connected to the ultrasound instrument, the peripheral including a keyboard, a mouse, etc. Further, if the current horizontal axis and / or the current vertical axis in the first section image of interest is located at or not located at the corresponding preset default position, the intersection of the current horizontal axis and the current vertical axis in the first section image of interest is determined, and the coordinates of the intersection are determined as the coordinates of the center point of the axis of the first section image of interest. That is, regardless of whether the current horizontal axis and the current vertical axis in the first section image of interest are located at the corresponding preset default positions, the coordinates of the axis center point of the first section image of interest can be determined by determining the intersection of the current horizontal axis and the current vertical axis in the first section image of interest and the corresponding coordinates.

[0074] In this embodiment, a plurality of second slice images of interest are obtained from the three-dimensional ultrasound data based on the axis center point coordinates, such as Figure 4As shown, three-dimensional ultrasound data is acquired, and a screen coordinate system is constructed based on the slice image displayed on the current display screen, and an object coordinate system is constructed based on the three-dimensional ultrasound data. By calculating the inverse transformation matrix between the screen coordinate system and the object coordinate system, and using the inverse transformation matrix to perform matrix transformation on the axis center point coordinates, the slice coordinate vectors of the screen coordinate system to the several target slices on the three-dimensional ultrasound data are determined, and the slice coordinate vectors are used to interpolate the three-dimensional ultrasound data to extract several second slice images of interest corresponding to the several target slices.

[0075] Step S13: drawing a corresponding niche image based on the axis center point coordinates, the first section image of interest, and the plurality of second section images of interest.

[0076] In this embodiment, after determining several second section images of interest, the first section image of interest and several second section images of interest are spatially recombined and image rendering is performed with the coordinates of the axis center points in the first section image of interest as connection points to draw the corresponding niche shadow images, and the niche shadow images are displayed in a dedicated niche shadow image display window on the current display screen so that the user can view the internal three-dimensional structure near the axis center point in the first section image of interest.

[0077] It should be noted that, in the first case, the plurality of second section images of interest are two mutually perpendicular section images of interest; and each second section image of interest is respectively perpendicular to the first section image of interest, that is, the three section images of interest are mutually perpendicular section images. In the second case, the plurality of second section images of interest are not limited to two section images of interest. When drawing a three-dimensional niche image, any two-dimensional section images of interest can be selected from the plurality of second section images of interest to be combined with the first section image of interest to generate a niche image. In either case, a three-dimensional niche image can be obtained by using the center point corresponding to the coordinates of the axis center point of the first section image of interest as the connection point of the three-dimensional section images of interest, and combining and connecting the single-dimensional first section image of interest and the other two-dimensional second section images of interest at the connection point according to the spatial structure and multi-dimensional distribution, and rendering the image.

[0078] Among them, for obtaining the slice number of interest based on the displayed multi-slice image by using the preset slice selection tool, in the first case, the multi-slice image is displayed on the current display screen in the form of thumbnails so that the user can intuitively view each slice image in the multi-slice image, and the thumbnails carry the corresponding slice numbers; the user clicks on any thumbnail displayed on the current display screen, that is, when the ultrasound instrument detects a click event on any thumbnail displayed on the current display screen, the slice number corresponding to the clicked thumbnail is determined as the slice number of interest, so as to determine the target storage address based on the slice number of interest, and use the target storage address to read the corresponding slice image from the memory as the first slice image of interest. In the second case, the multi-slice image is displayed on the current display screen in the form of thumbnails, and the thumbnails carry the corresponding slice numbers, and the user enters the slice number in the text box displayed on the current display screen, so as to directly determine the input slice number as the slice number of interest, so as to use the target storage address determined based on the slice number of interest to read the corresponding slice image from the memory as the first slice image of interest.

[0079] Among them, the target storage address is determined based on the slice number of interest, including determining the corresponding slice length and slice width based on the number of image display frames in the current display screen; determining the offset address based on the slice number of interest, the slice length and the slice width; determining the base address for storing multi-slice images from the memory, and determining the target storage address based on the base address and the offset address. It should be noted that in the process of multi-slice imaging of three-dimensional ultrasound data, the multi-slice images obtained by multi-slice imaging have been saved in the memory, and the required image data can be directly obtained from the memory in actual use. However, since the data of the multi-slice image is stored continuously in the memory, it is necessary to calculate the offset address according to the slice number of interest, so as to determine the target storage address based on the offset address, so as to read the slice image corresponding to the memory address from the memory as the first slice image of interest. Specifically, the correspondence between the number of image display frames and the slice length and slice width is preconfigured, so that after the number of image display frames displayed on the current display screen is obtained, the slice length and slice width corresponding to the number of image display frames are determined based on the correspondence; the slice number of interest, the slice length and the slice width are multiplied to obtain the corresponding offset address; the target storage address is calculated based on the offset address and the base address for storing multiple slice images in the memory, so as to read the slice image corresponding to the memory address from the memory as the first slice image of interest.

[0080] Take the combination of three slice images of interest to generate a niche image as an example. Figure 5As shown, the present application determines any single-dimensional main section image based on three-dimensional ultrasound data, adjusts the number of sections and the section distance through a preset configuration interface, and determines a number of parallel and equidistant cutting guide lines corresponding to the position of interest in the main section image based on the number of sections and the section distance, and uses a number of parallel and equidistant cutting guide lines to perform multi-section imaging on the three-dimensional ultrasound data, so as to determine the multi-section image based on the section images corresponding to each cutting guide line. By displaying the multi-section image in the form of thumbnails on the current display screen, it is convenient for users to observe each section image in the multi-section image, wherein the thumbnails carry the corresponding section numbers. When a click event for any thumbnail displayed on the current display screen is detected, the section number corresponding to the clicked thumbnail is determined as the section number of interest, so as to determine the target storage address based on the section number of interest, so as to use the target storage address to read the corresponding section image from the memory as the current section image of interest. Furthermore, by determining the coordinates of the center point of the current axis in the current slice image of interest, the inverse matrix of the transformation between the screen coordinate system and the object coordinate system is used to perform matrix mapping on the coordinates of the center point of the current axis, thereby determining the slice coordinate vectors of the target slices of the other two dimensions from the screen coordinate system to the three-dimensional ultrasound data, and interpolating the three-dimensional ultrasound data using the slice coordinate vectors to obtain two slice images of interest corresponding to the target slices of the other two dimensions, that is, the current slice image of interest and the slice images of interest of the other two dimensions are mutually perpendicular slice images. Based on the coordinates of the center point of the current axis in the current slice image of interest, the current slice image of interest and the slice images of interest of the other two dimensions, the corresponding niche image is drawn, and the niche image is displayed in a dedicated niche image display window in the current display screen. Combined with Figure 6 , Figure 7 and Figure 8 As shown, the three schematic diagrams show the multi-slice image schematic diagrams obtained by performing multi-slice imaging on three-dimensional ultrasound data under different image display numbers, different slice distances and slice numbers, and based on any slice image in the multi-slice image, the corresponding axis center point coordinates and the slice images of the other two dimensions can be automatically determined, so as to recombine and generate a niche image according to the spatial structure and display it in the lower right corner window of the display screen.

[0081] Taking ultrasound diagnostic equipment as an example, the original ultrasound data of the detected tissue is collected by the ultrasound probe in the ultrasound diagnostic equipment, and the original ultrasound data is transformed by the digital scan converter to obtain three-dimensional ultrasound data. The main section image is determined based on the three-dimensional ultrasound data, and the three-dimensional ultrasound data is multi-section imaged using a number of cutting guide lines for the position of interest in the main section image determined based on the section distance and the number of sections to obtain a multi-section image, and any section image is selected from the displayed multi-section image as the first section image of interest; the axis center point coordinates of the first section image of interest are obtained, and a number of second section images of interest are obtained from the three-dimensional ultrasound data based on the axis center point coordinates; the first section image of interest and the number of second section images of interest are combined according to the spatial structure based on the axis center point coordinates to obtain the corresponding niche image.

[0082] Taking an ultrasound imaging workstation as an example, three-dimensional ultrasound data collected and transmitted by an external device, such as an ultrasound diagnostic instrument, is obtained, a main section image is determined based on the three-dimensional ultrasound data, and a number of cutting guide lines set in parallel and at equal distances for the position of interest in the main section image are determined based on the section distance and the number of sections. The three-dimensional ultrasound data is imaged in multiple sections using the multiple cutting guide lines to determine the multiple section images based on the section images corresponding to each cutting guide line; any section image is selected from the displayed multi-section images as a first section image of interest; the axis center point coordinates of the first section image of interest are obtained, and a number of second section images of interest are obtained from the three-dimensional ultrasound data based on the axis center point coordinates; the first section image of interest and the number of second section images of interest are combined according to the spatial structure based on the axis center point coordinates to obtain a corresponding three-dimensional niche image.

[0083] It can be seen that after performing a multi-slice imaging of the three-dimensional ultrasound data, the present application selects any slice image of interest from the displayed multi-slice images, and automatically positions the corresponding other slice images of interest according to the axis center point coordinates of the slice image of interest, thereby automatically combining the selected slice image of interest and the automatically positioned other slice images of interest into a niche image according to the spatial structure. This not only facilitates the user to observe the internal three-dimensional structure corresponding to any slice image in the multi-slice images, but also supports the user to arbitrarily switch the slice image of interest selected from the multi-slice images, thereby realizing rapid adjustment of the niche image corresponding to the slice image of interest.

[0087] The niche image drawing module 13 is used to draw the corresponding niche image based on the axis center point coordinates, the first section image of interest and the plurality of second section images of interest.

[0088] It can be seen that after performing a multi-slice imaging of the three-dimensional ultrasound data, the present application selects any slice image of interest from the displayed multi-slice images, and automatically positions the corresponding other slice images of interest according to the axis center point coordinates of the slice image of interest, thereby automatically combining the selected slice image of interest and the automatically positioned other slice images of interest into a niche image according to the spatial structure. This not only facilitates the user to observe the internal three-dimensional structure corresponding to any slice image in the multi-slice images, but also supports the user to arbitrarily switch the slice image of interest selected from the multi-slice images, thereby realizing rapid adjustment of the niche image corresponding to the slice image of interest.
