虚拟心脏介入手术系统的血流模拟

虚拟心脏介入手术系统的血流效果模拟是系统中模型模拟的关键。实时而准确的血液流动效果增强了虚拟手术系统的真实感。在分析心血管内的血液流动物理模型的基础上,结合弹性腔模型,采用了改进的粒子系统方法,建立和实现了新的虚拟心脏介入手术系统的血流模型,满足了心脏介入系统的实时性和真实感要求。

Simulation of Blood Flow in Virtual System of Cardiac Intervention

Simulation of blood flow is a very important component in the virtual system of cardiac intervention system.Real-time and accurate simulation of blood flow can make the virtual surgery more realistic.This paper addresses the problem of the simulation of blood flow in virtual cardio-vascular objects.With an analysis of the physical model of cardiac-vascular blood flow in the artery based on the Windkessel model and by drawing the blood with improved particle system,this research successfully simulated the blood flow inside the vascular,thus satisfying the need of being real-time and realistic for the Cardiac intervention system.
