[0002] The fundus is the only image in the human body that can be used to simply, non-invasively and clearly observe changes in capillaries. According to incomplete statistics, more than 60 types of fundus diseases or systemic chronic diseases can cause corresponding lesions in the fundus, so fundus images are usually also a reference for the clinical diagnosis of these diseases.

At present, there is no suitable method to visualize the curvature of the blood vessels so that doctors and patients can better observe the changes in the curvature of the blood vessels.

For example, the blood vessels in the fundus image include main blood vessels, branch blood vessels, arteries, veins, etc. The blood vessels around the optic disc, the blood vessels around the macula, or the blood vessels around the lesions all need to know their curvature in detail.

Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] According to one embodiment of the present invention, Figures 1 to 4 Shown.

[0021] like Figure 1 As shown, a visualization system for a vascular tortuosity image includes a human-computer interaction module 101, an image processing module, an image acquisition module 103, and a main control chip 104; the main control chip 104 is respectively connected to the image acquisition module 103 and the human-computer interaction module 101 for communication, the image acquisition module 103 includes at least two I / O interfaces, the image acquisition module is connected to the corresponding image processing module through different I / O interfaces, and the image processing module is connected to the display terminal 106;

[0022] The human-computer interaction module 101 is used to receive a user trigger and send the user trigger to the main control chip 104; the main control chip 104 is used to control the image acquisition module 103 to send the target blood vessel image to the corresponding image processing module through the I / O interface according to the user trigger; the image processing module is used to perform image processing on the target blood vessel image based on image processing technology to generate a blood vessel curvature thermal image; and send the blood vessel curvature thermal image to the display terminal.

[0023] Here, the image acquisition module can be a device that exists independently outside the visualization system, or it can be a module that exists in the visualization system, such as a camera, an industrial camera, etc.

[0024] The main control chip module is a flash control chip or an 8051 CPU.

[0025] Specifically, the image acquisition module periodically acquires the target blood vessel image. The main control chip 104 first receives the user trigger through the human-computer interaction module 101, and controls the image acquisition module 103 to send the target blood vessel image to the corresponding image processing module through the I / O interface according to the user trigger. The image processing module performs image processing on the target blood vessel image based on the image processing technology, generates a thermal image of the blood vessel curvature, and sends the thermal image of the blood vessel curvature to the display terminal.

[0026] For example, the image acquisition module 103 includes a first I / O interface 105 and a second I / O interface 106; the image processing module includes a first image processing module 107 and a second image processing module 108; the display terminal includes a first display terminal 102 and a second display terminal 109.

[0028] It should be noted that the target blood vessel image may be a target fundus image, or an image of another target part; no limitation is imposed here.

[0029] Compared with the single digital output form, the system of this embodiment displays the thermal image of blood vessel curvature in a visual manner, which is convenient for doctors and patients to observe and understand; and the two-dimensional visualization method of this embodiment has lower data storage costs than the three-dimensional visualization method, so it can display and analyze blood vessel morphology at a lower cost, especially in medical image analysis reports, which has its unique value.

[0030] like Figure 3 , which is a schematic diagram of a thermal image of the vascular curvature corresponding to the target fundus image; wherein the bright area represents the area where the vascular curvature is abnormal, and the brighter the color, the greater the curvature.

[0031] In a preferred implementation of this embodiment, the first display terminal includes a display screen module; the display screen module includes a plurality of display areas determined according to a preset splicing mode, and each display area is used to display the first blood vessel tortuosity thermal image. The display screen module is used to display the plurality of the first blood vessel tortuosity thermal images in the first buffer area in multiple screens through the display screen based on the preset splicing mode.

[0032] Specifically, the first blood vessel curvature thermal images corresponding to the target blood vessel images of the same target object at different times are obtained; and the first blood vessel curvature thermal images at different times are displayed in multiple screens according to a preset splicing mode. Thus, the multi-screen display of the display module improves the user experience and facilitates the doctor's diagnosis of the disease.

[0033] It should be noted that the first display terminal and the second display terminal have the same structure; the first image processing module and the second image processing module have the same unit structure, which will not be repeated here.

[0034] In another preferred embodiment of this embodiment, Figure 2 FIG. 1 is a schematic diagram of the structure of a first image processing module provided in an embodiment of the present utility model.

[0036] Specifically, the human-computer interaction module receives a user trigger and sends the user trigger to the main control chip; the main control chip controls the image acquisition module according to the user trigger to send the first target blood vessel image to the first GPU through the first I / O interface, and sends the second target blood vessel image to the second GPU through the second I / O interface.

[0037] The image acquisition module of this embodiment sends the target blood vessel images corresponding to different target objects to the corresponding image processing modules through different I / O interfaces. Each image processing module performs image processing on the received target blood vessel images in parallel through the internal CPU. Therefore, the system can process different target blood vessel images in parallel at the same time, thereby improving the processing speed of the target blood vessel images; it is beneficial for the system to visualize the thermal image of the blood vessel curvature corresponding to the target blood vessel image, thereby improving the user experience.

[0038] In a preferred implementation of this embodiment, the first image processing module 107 includes an image processing unit 1101, an image rendering unit 1102, and an image fusion unit 1103; the image processing unit 1101, the image rendering unit 1102, and the image fusion unit 1103 are all physical processing units set on the first CPU. The image processing unit 1101 is used to obtain the vascular centerline of the target vascular image from the first target vascular image; and for any pixel point on the vascular centerline: replace the original gray value with the curvature value corresponding to the pixel point to generate a replacement result; the image rendering unit 1102 is used to render the vascular centerline based on the replacement result of each pixel point on the vascular centerline to generate a centerline curvature image; the image fusion unit 1103 is used to perform fusion processing based on the target vascular image and the centerline curvature image to generate a vascular curvature thermal image.

[0039] The image processing module of this embodiment performs grayscale value conversion processing on the curvature value on the blood vessel centerline, which is conducive to replacing the original grayscale value on the blood vessel centerline, thereby providing a basis for the visualization of the blood vessel curvature and improving the visualization effect of the blood vessel curvature thermal image.
