Problems solved by technology

[0003] In clinical practice, coronary angiography images can be obtained by injecting contrast agent enhancement. However, due to the different thickness of blood vessels, the contrast dose distribution in blood vessels is different, resulting in different gray values ​​displayed by calcified plaques.

Abstract

The present disclosure relates to a method and device for detecting coronary artery calcified plaques. The method includes: performing segmentation processing on an image to be processed, and determining multiple target areas of the first organ in the image to be processed; for any target area, according to the target area According to the grayscale information of the target area, determine the first grayscale threshold and the second grayscale threshold; according to the first grayscale threshold and the second grayscale threshold of the target area, respectively determine the suspected lesion area and the pseudo lesion area in the target area ; Determining the lesion area of ​​the first organ according to the suspected lesion area and the pseudo lesion area of ​​each target area. According to the embodiments of the present disclosure, not only can effectively reduce the omission of calcified plaques in small branch vessels of coronary vessels in the image to be processed, improve the recall rate of calcified plaques, but also significantly improve the accuracy of calcified plaque identification.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, in particular to a method and device for detecting coronary calcified plaque. Background technique [0002] Cardiovascular disease is a disease that seriously endangers human health. Most cardiovascular diseases are caused by atherosclerotic plaques. Calcified plaque in coronary arteries is a sign of the degree of atherosclerosis, which can predict the possibility of coronary artery disease in patients. [0003] In clinical practice, coronary angiography images can be obtained by injecting contrast agent enhancement. However, due to the different thickness of blood vessels, the distribution of contrast dose in blood vessels is different, resulting in different gray values ​​displayed by calcified plaques. Contents of the invention [0004] In view of this, the present disclosure proposes a method and device for detecting coronary calcified plaque. [0005] According to an asp...
