Abstract: Abstract One of the most challenging applications of simulations in medicine is the use of Computational Fluid Dynamics (CFD) to simulate vascular hemodynamics and visualize the resulting complex flow patterns so that physicians can better understand and plan the treatment of patients with life-threatening vascular diseases such as brain aneurysms. It is now possible to acquire high-resolution images of the brain, and to subsequently create detailed 3D models of aneurysm geometry. CFD methods are used to calculate vascular flow patterns in the aneurysm, including fluid velocity and wall pressure and strain. Virtual-reality visualization techniques are then used to enable the physician to interactively explore vascular geometry and flow patterns in an immersive environment. The resulting simulation data and visualization techniques are helping medical researchers to develop new theories and tools to better organize and understand the complex anatomy and physiology of human brain vasculature.
