3D Geometric Reconstruction of Coronary Stented Artery

Abstract

Coronary artery disease is a narrowing of lumen in the coronary artery usually resulting in permanent heart muscle damage or heart attack. Intravascular stents are tubular structures placed into stenotic artery to expand the inside passage and improve blood flow. The mechanical factors affect the restenosis after stenting and image-based simulation has become a popular tool for acquiring information. The study aims to provide physicians with a feasible method for 3D entity reconstruction of coronary stented artery. The coronary artery images derived from patient before and after stenting were processed by Mimics for image segmentation and 3D reconstruction. The coronary blood and wall were constructed, as well as the stented artery model. The model can be used for hemodynamic and fluid structure interaction simulation.
