Blood Flow Visualization

In this project we are developing and evaluating scientific visualization methods for exploring the complicated, time-varying, 3D structure of arterial blood flow. This research explores not only novel visual representations and interactive techniques, but also virtual reality environments that can enhance perception of the scientific phenomena.

Project status: Active
