中文摘要：

由于脑的纸巾是高度不规则的，三维(3D ) 大脑当模特儿总是导致复杂计算。在这份报纸，我们探索一个有效方法因为从磁性的回声(先生) 的大脑表面重建头想象，它对外科计划和肿瘤本地化有用。一个启发式的算法与保存特征为表面三角网孔产生被建议，并且斜长度被认为是启发式的信息优化三角的形状。试验性的结果显示出那我们的途径不仅减少计算复杂性，而且与好质量完成 3D 可视化。

英文摘要：

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.
