摘　　要：作者基于CT图像处理后 ,对处理结果采用数学中常用的插值算法进行轮廓曲线的逼近分析 ,分别对拉格郎日插值、牛顿多项式插值、埃尔米特插值、样条函数插值等多种插值方式应用于骨科三维造型中的优缺点 ,从算法本身到算法对于医学要求的适用程度进行了比较 ,较为全面地阐述了设计人员在骨科三维造型中使用插值算法会碰到的一系列问题。Based on the result of processing CT image, various interpatation algorithm,including Lagrange interpretation? Newton interpretation? Hermite interpretation and Spline interpretation etc, are applied to set up the outline's curve. Each algorithm's merit and demerit are compared from itself to its' applicability for medicine. A series of problem, which will be faced during the course of 3D design, are discussed roundly in this thesis.
