Abstract: Virtual colonoscopy is a non-invasive computerized medical procedure for examining the entire colon to detect polyps.We present an interactive virtual colonoscopy method, which uses a physicallybased camera control model and a hardware-assisted visibility algorithm.By employing a potential field and rigid body dynamics, our camera control supplies a convenient and intuitive mechanism for examining the colonic surface while avoiding collisions.Our Zbuffer-assisted visibility algorithm culls invisible regions based on their visibility through a chain of portals, thus providing interactive rendering speed.We demonstrate our method with experimental results on a plastic pipe phantom, the Visible Human, and several patients.
