A directed particle system for optimised visualization of blood flow in complex networks

Abstract

This paper introduces a novel technique for the visualization of blood (or other fluid) flowing through a complex 3D network of vessels. The Directed Particle System (DPS) approach is loosely based on the computer graphics concept of flocking agents. It has been developed and optimised to provide effective real time visualization and qualitative simulation of fluid flow. There are many potential applications of DPS, and one example-a decision support tool for coronary collateralization-is discussed. © 2013 The authors and IOS Press.
