Abstract

The article is dealing with novel and relatively complex computer system for automatic creation of human tissues geometrical models. Applications of the created mod els can be found in orthopedy, aesthetic surgery, dental surgery, etc. On the input are discrete volume CT/MR data in DI COM 3.0 data format. The models creation process con sist of several steps: tissue segmentation, volume data vectorization by Marching cubes method, triangular mesh smoothing and export into desired data representation, which depend on particular application. The geometrical models can be exported into CAD/CAM/FEM systems as polygonal, polysurfaces or tetrahedral meshes.
