Interactive Virtual Navigation in Human Organs

摘要

Virtual endoscopy is meaningful for medical diagnosis and surgery. In this paper, a system framework for virtual endoscopy is proposed including automatic centerline extraction and view-dependent level-of-detail rendering techniques. Combining Hessian Matrix with distance mapping, our path planning method can generate accurate skeleton for virtual navigation. Furthermore, real time rendering can be achieved with our new view-dependent subdivision algorithm. The experimental results show the efficiency of our methods.
