在距离变换阶段，该方案采用了一种新的三维欧氏距离变换算法，在保证距离测量精度的同时缩短了运算时间。
To reduce the computation time, a new 3d Euclidean distance transformation algorithm was adopted to compute the distance map of the medical image.
欧氏距离法的重建效果比小波变换法要差一些，所用时间比小波变换法要少的多；
The performance of Euclidean Distance is inferior to Wavelet Transform, but using much less time, Maximal Distance gets the worst result , while taking the least time.
