摘 要:Due to the encephalic tissues are highly irregular, three-dimensional (3D) modeling of brain always leads to compli- cated computing. In this paper, we explore an efficient method for brain surface reconstruction from magnetic reso- nance (MR) images of head, which is helpful to surgery planning and tumor localization. A heuristic algorithm is pro- posed foi" surface triangle mesh generation with preserved features, and the diagonal length is regarded as the heuristic information to optimize the shape of triangle. The experimental results show that our approach not only reduces the computational complexity, but also completes 3D visualization with good quality.
关 键 词:Heuristic algorithms Magnetic resonance imaging Mesh generation Surface reconstruction Three dimensional computer graphics
