医学图像重建MC算法三角片的合并与实现

Triangle Merging and Accomplishing of Medical Image Reconstruction Based on MC Algorithm

提出一种算法对MarchingCubes算法中产生的大量三角片进行合并。根据三角片顶点的空间位置,按照所给的约束条件对顶点进行判断,合并符合条件的顶点,以减少三角片的数目。这个方法在保留图像细节的前提下,改善影像的显示速度,以期实现三维医学图像实时显示。对数据量大的医学图像的三维重建尤为必要。

The algorithm proposed in this paper merges the enormous triangle vertexes generated by the Marching Cubes algorithm. Based on the spatial position of triangle vertexes, it merges the vertexes accord with the constraint to reduce the number of triangles. This algorithm can realize the realtime display of the threedimensional medical image while remaining image details. It is vital to the medical images with a large amount of data.
