Problems solved by technology

Among them, the effect of coronary artery reconstruction depends on the extraction and separation of coronary arteries, and the extraction and separation of small branch coronary arteries is difficult and time-consuming, especially when the stenosis rate of a certain coronary artery reaches 100%. If it is completely blocked, the

Embodiment 1

[0029] figure 1 It is a flow chart of a plaque detection method provided in Embodiment 1 of the present invention. This embodiment is applicable to plaque detection. The method can be executed by a plaque detection device, and specifically includes the following steps:

[0030] S110. Acquire a sequence of coronary artery images to be detected.

[0031] Obtain the image sequence obtained after the coronary artery is scanned by the medical imaging equipment, perform windowing preprocessing on the obtained coronary artery image sequence, compress the pixel value of the image in the range of 0-255, so that only the coronary artery is displayed in the image sequence, etc. The necessary information can avoid the interference of other useless information on the detection of coronary artery plaques, improve the accuracy of plaque detection, and compress the pixel value range of the image to the preset range, which can avoid plaques caused by excessive pixel value changes. The patch d...

Embodiment 2

[0048] image 3 It is a flow chart of the plaque detection method provided by Embodiment 2 of the present invention. This embodiment is a further optimization of the previous embodiment. The plaque detection method further includes: treating the plaque according to the final plaque position included in the final plaque detection result The coronary artery image is detected for image segmentation to extract the coronary artery vessel where the plaque is located; the vascular stenosis rate is calculated based on the extracted coronary artery vessel. After performing plaque detection on the coronary artery image, image segmentation is performed on the coronary artery image with plaque to extract the coronary artery vessel where the plaque is located and calculate the stenosis rate, avoiding image segmentation on the coronary artery image without plaque, effectively reducing the The time and difficulty of blood vessel extraction.

Embodiment 3

[0061] Figure 4 A structural diagram of a plaque detection device provided in Embodiment 3 of the present invention, the plaque detection device includes: an image sequence acquisition module 310, an image combination generation module 320, an intermediate plaque detection result acquisition module 330, and a final plaque detection module Result determination module 340 .

[0062] Wherein, the image sequence acquisition module 310 is used to acquire the coronary artery image sequence to be detected;

[0063] An image combination generation module 320, configured to generate at least one coronary artery image combination to be detected according to the coronary artery image sequence to be detected, the coronary artery image combination to be detected includes at least two coronary artery images to be detected;

[0064] The intermediate plaque detection result acquisition module 330 is used to input the combination of the coronary artery images to be detected into the trained ...

Abstract

The embodiment of the invention discloses a plaque detection method and device, equipment and a medium. The method comprises the following steps: acquiring a to-be-detected coronary artery image sequence; generating at least one to-be-detected coronary artery image combination according to the to-be-detected coronary artery image sequence, wherein the to-be-detected coronary artery image combination comprises at least two to-be-detected coronary artery images; inputting the to-be-detected coronary artery image combination into a trained plaque detection model to obtain an intermediate plaque detection result of each to-be-detected coronary artery image; and determining a final plaque detection result based on the intermediate plaque detection result of each coronary artery image to be detected. According to the technical scheme, the problems that an existing coronary plaque detection technology is large in detection difficulty and inaccurate in detection are solved, and the effects ofreducing the coronary plaque detection difficulty and improving the plaque detection efficiency and accuracy are achieved.

Description

technical field [0001] Embodiments of the present invention relate to medical image technology, and in particular to a plaque detection method, device, equipment and medium. Background technique [0002] The coronary arteries are the arteries responsible for supplying blood to the heart. When atherosclerotic lesions occur in the coronary arteries, the lumen of the blood vessels will be narrowed or blocked, which in turn will cause myocardial ischemia, hypoxia or necrosis, which is commonly known as "coronary heart disease". . [0003] Coronary Computed Tomographic Angiography (CCTA) is a means of routine coronary artery examination. Through CCTA data, the location, nature and degree of stenosis of coronary atherosclerosis can be judged. Coronary atherosclerosis is divided into calcified plaque, non-calcified plaque, and mixed plaque with both calcified and non-calcified properties. [0004] At present, the commonly used methods for judging the nature of coronary artery pla...
