Plaque detection method, device, equipment and medium

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...

AI Technical Summary

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 result shown on the image is that one coronary artery is cut into two pieces. At this time, it may not be possible to extract the second piece of coronary artery, and subsequent coronary artery reconstruction will also fail.

Therefore, existing methods for judging the nature of coronary artery plaques are difficult and inefficient
