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 invention relates to a coronary artery calcification plaque detection method and device, and the method comprises the steps: carrying out the segmentation processing of a to-be-processed image, and determining a plurality of target regions of a first organ in the to-be-processed image; for any target area, determining a first gray threshold and a second gray threshold of the target area according to the gray information of the target area; respectively determining a suspected focus area and a pseudo focus area in the target area according to the first gray threshold and the second gray threshold of the target area; and determining the focus area of the first organ according to the suspected focus area and the pseudo focus area of each target area. According to the embodiment of the invention, omission of the calcified plaque at the small branch blood vessel of the coronary blood vessel in the to-be-processed image can be effectively reduced, the recall rate of the calcified plaque is improved, and the accuracy of identification of the calcified plaque can be remarkably improved.

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...
