Abstract

The present invention relates to the field of medical engineering technology, and in particular to a hemodynamic simulation analysis system for coronary stent implantation. The system includes a coronary vascular anatomical structure auxiliary design module, a coronary stent finite element model design module, a post-implantation hemodynamic simulation analysis module, and a blood flow state evaluation module before and after implantation. The system can obtain the patient's coronary medical imaging data and perform vascular anatomical structure geometry analysis and vascular three-dimensional model auxiliary design to generate a three-dimensional model of the patient's coronary vascular anatomical structure; generate a coronary stent finite element model through the design of the coronary stent geometry feature set, obtain the hemodynamic characteristic parameter set before stent implantation, perform blood flow boundary restriction analysis and coronary stent implantation dynamics simulation analysis, and simultaneously perform blood flow state evaluation analysis before and after stent implantation to generate a blood flow state simulation evaluation report before and after stent implantation. The present invention can efficiently and accurately analyze the changes in blood flow state after stent implantation.
