  1. But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data

    但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值,閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個動立方體來進行處理,就是說對所有的立方體都要進行一檢測,演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上,因此需要有一種合理的數據結構對空間數據進行有效的遍歷,以加速對空單元的檢測和過濾;標準mc演算法產了大量的三角片,一般重建的組織或器官包含數十萬甚至上百萬的三角片,難以實現實時的繪制和交互操作;標準mc演算法得到的表網格並不光,會有一些不期望的凹凸,特別是在原始數據有較大誤差的情況下尤其突出。
