任意方向上三维切割的实现

Three-dimensional Clipping in Arbitrary Direction

提出了一种通过对虚拟切片序列进行提取来实现任意方向上三维切割的方法,通过对重建三维体进行旋转,选择需要生成虚拟切片的部位的切入方向和切入点,就可以得到任意方向的虚拟切片.从实现结果可以看出,与传统的三维切割方法相比,该方法可以更好的节约存储空间且操作可具有更大的随意性.

This paper proposes a new method to accomplish three-dimensional clipping in arbitrary direction by extracting a sequence of virtual slices, We can get it by choosing appropriate entrance direction and point of penetra- tion. This method can economize the use of memory storage and reduce the restrictions on operation compared with traditional clipping methods.
