Problems solved by technology

However, due to the complex distribution of CT gray values ​​of coronary plaques, especially the CT values ​​of coronary soft plaques and enhanced blood vessel CT values ​​have a large overlap and intersection, it is difficult to use existing gray and gradient features to Segmentation of soft plaques, which brings great difficulty to the extraction of coronary plaques
Therefore, traditional techniques cannot accurately segment coronary plaques

Abstract

The invention relates to a patch segmentation method and device, computer equipment and a storage medium. A target coronary artery comprising a plurality of reference image blocks is collected, coronary artery plaque detection is performed on each reference image block in the target coronary artery through a preset plaque detection network, candidate reference image blocks are obtained, and then the obtained candidate reference image blocks are input into a preset plaque segmentation network to obtain he coronary plaque segmentation result of the candidate reference image block. According to the method, the recognition rate of coronary plaque detection can be improved, the edge detail segmentation of the coronary plaque can be more accurate, and the coronary plaque in each candidate reference image block can be quickly and accurately segmented.

Description

technical field [0001] The present application relates to the technical field of medical image processing, in particular to a plaque segmentation method, device, computer equipment and storage medium. Background technique [0002] Cardiovascular disease is a disease with high morbidity and mortality, and has the characteristics of acute onset and strong concealment. The main pathological basis of coronary heart disease is plaque, which can lead to narrowing of the coronary artery lumen until it is completely occluded. The diagnosis of heart disease has very important clinical significance. At present, with the improvement of CT imaging speed and scanning accuracy, CT medical imaging has been widely used in heart examination and plaque diagnosis. At the same time, in order to better realize the inspection of cardiovascular diseases, cardiac coronary artery segmentation and coronary plaque segmentation are widely used as auxiliary means, which can extract the contours of coro...
