Abstract

The invention provides a construction method of a three-dimensional coronary artery analysis model and a system thereof. The construction method of the three-dimensional coronary artery analysis model comprises the following steps of acquiring a two-dimensional tomoscan image of a heart; extracting a two-dimensional tomoscan image of a coronary artery blood vessel from the two-dimensional tomoscan image of the heart; carrying out three-dimensional reconstruction on the two-dimensional tomoscan image of the coronary artery blood vessel so as to obtain a three-dimensional coronary artery blood vessel model; based on the three-dimensional coronary artery blood vessel model, establishing the three-dimensional coronary artery analysis model used for engineering calculation. By using the method and the system, accuracy of three-dimensional coronary artery analysis model construction can be increased.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a method and system for constructing a three-dimensional coronary artery analysis model. Background technique [0002] Cardiovascular disease, also known as circulatory system disease, is a series of diseases involving the circulatory system. Cardiovascular disease is mainly due to the narrowing of blood vessels, which leads to insufficient blood supply to the heart. If a patient develops cardiovascular disease, symptoms such as chest tightness, palpitations, and syncope will occur, and in severe cases, myocardial infarction may also occur. [0003] In the existing medical imaging technology, the detection of vascular stenosis is still in the stage of interventional arteriography. It is necessary to place sensors, pressure guide wires, etc. to measure in the patient's body. Physical suffering, increased medical costs and increased risk of death for patients. ...
