摘　　要：虚拟手术训练系统的血流模拟是系统中模型模拟的重要部分。实时准确的血流流动效果,可以明显地增强虚拟手术训练系统的真实感。首先基于流体力学的Navier-Stokes方程的数值化解法,模拟血流流动的效果;然后在VTK框架中进行渲染,将血流模块集成到一个已有的、初步成熟的系统中;最后通过实验,表明血流模块的加入使系统的真实感得到较好的展现。Blood flow simulation in virtual surgery training system is an important part of model simulation in the system.The effect of blood flowing which is real-time and accurate enforces the realisticity of this training system.In this paper,we firstly research simulating the blood flowing effect based on numerical solution of Navier-Stokes equations of fluid mechanics theory.Secondly,we research on integrating the blood flow simulation modules into an existing and primarily mature system after rendering them in VTK frame.At last,we demonstrate through experiments that adding blood flow simulation modules makes the realisticity of the system present preferably good.
