At present, computer assisted surgery systems help orthopaedic surgeons both plan and perform surgical procedures. To enable these systems to function, it is crucial to have at one's disposal 3D models of anatomical structures, surgical tools and prostheses (if required). This paper analyses and compares three methods for generating 3D digital models of anatomical structures starting from X-ray images: parametric solid modelling/reconfiguration, global shape modelling and free-form deformation. Seven experiences involving the generation of a femur model were conducted by software developers and different skilled users. These experiences are described in detail and compared at different stages and from different points of view.
目前，计算机辅助手术系统帮助骨科医生规划和实施手术程序。为使这些系统发挥作用，掌握解剖结构、手术工具和假体（如有需要）的三维模型至关重要。本文分析并比较了三种从X射线图像生成解剖结构三维数字模型的方法：参数化实体建模/重构、全局形状建模和自由形式变形。软件开发人员和不同技能水平的用户进行了七次生成股骨模型的实践。详细描述了这些实践，并从不同阶段和不同角度进行了比较。
