We present an algorithm to compute the contour after cutting and interpolation of cut plane. Result shows that it can get ideal final image.
立体图象切割作为三维图象显示的一种有用的方式，可以提供剖面信息，便于诊断。

The basic ideas of the algorithm is due to concentrating of the brance-bound and the cutting-plane, but it decreases the number of the branch and simplifies the technique of the cutting-plane.
