Parallel implementation of vascular network modeling

Abstract

The paper presents modeling of the vascular system in a parallel environment. The aim of this approach is to accelerate the simulation of vascular network growth and make it closer to analogous real life processes. We concentrated on the perfusion process and made an attempt to parallelize the process of connecting ischemic macroscopic functional units to existing vascular systems. The proposed method was implemented on a computing cluster with the use of the MPI standard. The results show that it is possible to gain a significant speedup that allows us to make simulations for a greater number of macroscopic functional units and vessels in a reasonable time, which increases the possibility to create more complex and more precise virtual organs. © 2008 Springer-Verlag Berlin Heidelberg.
