Blood Flow Simulation System with Interaction between Blood Flow and Blood Vessel Wall using Image Based Cartesian Grid

Abstract

For the simulation of the fluid-structure interaction (FSI) between the blood flow and blood vessel walls, we have examined the voxel-based FSI method. This method uses a Cartesian grid, called voxel, made from medical images. Further, we have tested the accuracy and reliability of this simple method and have observed its features. In this document, we discuss the background, kinetic models of the blood vessel, a numerical method, and the result of an experiment conducted using an artificial identical shape and an actual realistic shape.
