Research progress in tetrahedral mesh generation from medical volume data
医学体数据中四面体化方法的研究进展*

Tetrahedral mesh generation has always been a hot issue in the area of mesh generation, but its application in geometrical construction of organs from medical volume data is still very difficult. This paper first gave an introduction to the state-of-art of the Marching cubes which was the most popular isofacing algorithm. Then, according to different preprocessing for medical volume data, summarized and compared three types of tetrahedral mesh generation in their developments, extension and limitations (including the attempts to resolve its limitations) through classic examples. Especially, analyzed and reviewed some novel algorithms based on Delaunay in detail. Along existing methods, predicted some potential directions for future research finally.
