Abstract

The invention provides a method and device for synthesizing a blood vessel mathematical model with a stenosis lesion, and the method comprises the steps: carrying out the three-dimensional modeling according to the real-time diameter Dt of a blood vessel, the length L of a central line of the blood vessel, and a stenosis region, and forming a three-dimensional blood vessel model with the stenosislesion region; performing N-sided mesh generation along the circumferential surface of the three-dimensional blood vessel model to form a single-layer mesh model; and performing surface layering processing on the single-layer grid model to form a double-layer grid model, namely a blood vessel mathematical model. The problem that no blood vessel three-dimensional grid model for hydromechanics analysis exists in the prior art is solved, and the blank of the industry is filled up; due to the fact that the blood vessel wall has a certain thickness and the problem of stenosis mainly occurs on the inner wall of the blood vessel, the blood vessel mathematical model is built into the double-layer grid model, the double-layer grid model has a certain thickness, the inner-layer grid model has elasticity, the blood flow velocity can be corrected, and the blood vessel model is closer to the real state of the blood vessel.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a method, device and system for synthesizing a mathematical model of blood vessels with narrow lesion intervals for fluid mechanics analysis. 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 coronary angiogra...
