Abstract

This paper presents a deformable hollow organ model considering the self-collision between the inner surfaces of a hollow organ for real-time surgical simulation. The hollow organ was modeled by the finite element method with 10400 tetrahedral elements, 2160 nodes, and 1040 inner meshes. In the model, the continuous collision detection is performed between the inner surfaces to prevent penetrations of them. As a result, it was shown that the model is well-behaved about 40 fps by a standard PC with Pentium4 3GHz and 2GB RAM.
