A Virtual Environment for Core Skills Training in Vascular Interventional Radiology

摘要

We present a prototype for a new virtual environment aiming at training interventional radiologists in the core skills involved in using catheters or guidewires. The instrument is modelled as a hybrid mass-spring particle system while the vasculature is a rigid triangulated surface mesh. A specially designed commercial haptic device allows the trainee to use real instruments to guide the simulation through synthetically generated vasculature with different degrees of complexity. Open source libraries are used for the visualisation and collision detection. Preliminary results show reasonable behaviour.
