The Virtual Aneurysm is a simulation and virtual reality visualization of brain blood flow. Using a software system that will be able to accurately model an aneurysm imaged using x-ray computed tomographic angiography (CTA), a doctor can visualize the aneurysm in a virtual reality environment, predict its future behavior, and gain insight into the type of treatment needed. Cutting planes and stream lines tools can to be used to examine the pressure, fluid velocity, and shear forces of the aneurysm. Researchers are working to improve the accuracy of blood flow simulations, and on the development of intelligent tools to enable doctors to more easily visualize critical flow patterns and to evaluate simulated surgical interventions. Internet2 high-performance networking provides the advanced capabilities (high-bandwidth and low delay) necessary to enable the remote visualization and navigation of multi-terabyte virtual aneurysm simulations stored on a high-performance server at UCLA.
