Abstract

The invention provides a method, a device and a system for acquiring a vascular stenosis lesion interval and performing three-dimensional synthesis. A blood vessel center line is extracted from coronary artery two-dimensional contrast images of the at least two body positions in the direction from the coronary artery inlet to the coronary artery tail end; A straightened blood vessel image is acquired according to the coronary artery two-dimensional contrast image and a blood vessel center line; a straightened blood vessel contour line is acquired according to the straightened blood vessel center line and the straightened blood vessel image; geometric information of the straightened blood vessel is acquired. Three-dimensional modeling is carried out according to the geometric information, the center line and the contour line to obtain a three-dimensional blood vessel model with a narrow lesion interval. The stenosis lesion interval is stereoscopically displayed to a patient and a doctorin a three-dimensional blood vessel model mode, the stenosis lesion interval is more vivid, all angles of the stenosis lesion can be displayed, the influence of the shooting angle of the two-dimensional radiography image on the judgment result of coronary artery stenosis is reduced, and the stenosis lesion area of the blood vessel can be accurately judged.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a three-dimensional modeling method and device for blood vessels with narrow lesion intervals, a coronary artery analysis system and a computer storage medium. Background technique [0002] The deposition of lipids and sugars in human blood on the blood vessel wall will form plaques on the blood vessel wall, which in turn will lead to vascular stenosis; especially the vascular stenosis near the coronary artery of the heart will lead to insufficient blood supply to the myocardium and induce coronary heart disease , angina pectoris and other diseases pose a serious threat to human health. According to statistics, there are about 11 million patients with coronary heart disease in my country, and the number of patients treated with cardiovascular interventional surgery is increasing by more than 10% every year. [0003] Conventional medical detection methods such as...
