摘要
本文基于股骨头与髋臼配合作用面为半球面的前提，提出一种根据股骨头横截面ＣＴ片轮廓确定股骨头几何中心的轴向位置，进而确定股骨头空间几何中心坐标及股骨头直径的方法。
A new method is presented in this paper to determine the spacial position of the femur head with the CT images of the femur,The approach is based upon the hypothesis that the contacting part of the femur head with the acetabulum is nearly spherical
