Abstract

The invention relates to a coronary artery calcification plaque segmentation method, a coronary artery calcification integral calculation method and a computer readable storage medium. The method comprises the following steps: acquiring a first medical image of a heart area; classifying each voxel of the first medical image by using a preset segmentation model to obtain a first classification result of classifying each voxel according to a parent category and a second classification result of classifying each voxel according to a subcategory; according to the parent category of each voxel in the first medical image, correcting the subcategory of each voxel in the first medical image to obtain a third classification result; and obtaining a coronary artery calcification plaque segmentation result of the first medical image according to the third classification result. According to the method and the device, the problem of low robustness of a coronary artery calcification plaque segmentation method in related technologies is solved, and the robustness of coronary artery calcification plaque segmentation is improved.

Description

technical field [0001] The present application relates to the field of image segmentation, in particular to a method for segmenting coronary calcified plaques, a method for calculating coronary calcification points, and a computer-readable storage medium. Background technique [0002] Cardiovascular disease (CVD) is the most common cause of death worldwide. The degree of calcification of calcified plaques in coronary arteries is an important indicator for monitoring cardiovascular diseases, and is also an important means for predicting cardiovascular diseases. The calcification score calculated according to the plain heart scan image is an evaluation index reflecting the degree of calcification in the coronary artery. It is difficult to see the position of the coronary arteries in plain heart scan images because they are not enhanced, and there is a lack of electrocardiogram (ECG) synchronization, and heart motion artifacts and scan doses will also generate image noise. Th...
