| 摘 要： | 以踝关节的生理解剖结构为理论依据，利用踝关节的CT图像作为二维数据源，通过医学图像处理软件Mimics建立踝关节的三维模型，然后使用3-matic对三维模型的网格进行优化，最后对优化前后的模型进行对比分析。结果发现经过优化后的踝关节三维模型在结构上与人体真实的踝关节结构并无明显的差异，精确程度满足要求，对于患者病情的分析及治疗方案的确立具有重要的指导意义。

| Abstract: | Abstract: Based on the physiological and anatomical structures of the ankle joint, the CT image of the ankle joint is used as the two-dimensional data source to establish the three-dimensional (3D) model of the ankle joint by medical image processing software Mimics, and the mesh of the 3D model is optimized by 3-matic. Finally, the models before and after optimization are compared and analyzed. The results reveal that the optimized 3D model of the ankle joints has no obvious difference from the real ankle structure, and its accuracy meets the requirements, which has great significance in the analysis of patients condition and the establishment of treatment plan. |
