Visualization of the Stress Distribution according to the Aorta Valve Deformation

Abstract

We have performed a particle based simulation on deformation of the aorta valve and blood flow for medical education. The proposed method treats not only blood but also blood vessel and the aorta valve as a set of particles, and calculates the stress between particles with an uniform method. In addition, we have used Herschel-Bulkley model as constitutive equation of blood, and have simulated the blood flow according to the aorta valve deformation. One step simulation time including rendering was about 70ms for the deformation of the aorta valve with the model that is constructed with 4,300 particles for the aorta valve, blood vessel and blood itself.
