Building a surface geometry model is one of the key technologies for realizing the sense of reality in virtual surgery simulation.Currently,the surface model is constructed mainly by the isosurface algorithm.In this paper,a more sophisticated image segmentation algorithm is used to extract the edge of tissues,thereby reducing the possibility of a narrow triangle which may appear when carrying out triangulate segmentation,improving the accuracy of isosurface,preventing cavities in the surface model,and enabling the tissue's model to be more realistic.

Key words: surface model;triangulate;contour;isosurfaces
