摘要
针对现有医学图像特点,提出了一种医学三维建模的新方法。该方法基于传统MC算法,结合种子填充思想进行等值面扩展,并利用DMC方法进行插值位置取代,最后直接连接等值点生成多边形网,从而减少了面片数量,很好的解决了二义性问题。实验表明,该方法较传统方法在拓扑结构、存储空间和处理速度方面均有较大改善。
An approach which is grounded on the traditional Marching Cubes algorithm is proposed for medical three- dimensional reconstruction based on the characteristics of modern medical image. This method, combined with seed - occupying algorithm to expand isosurface, replaces cell edge interpolation by midpoint selection with DMC and orders isopoints directly in predefined cases polygons, which reduces the number of faces and solves the ambiguity problem. The experiment results show that the proposed approach makes a great improvement on topological structure, storage space and processing speed.
