摘要：

背景：克服传统标本力学分析的不利因素，建立逼真的足部各结构有限元模型，是对足部进行有限元力学分析的重要基础。
目的：建立足部的三维有限元数字模型，为正常足部及足部损伤情况下的有限元力学分析打基础。
方法：对1名健康女性志愿者行双足螺旋CT扫描，将所得图像在Mimics软件中重建三维模型，在Geomagic软件中生成实体模型，最后在Ansys中建立足主要结构的三维有限元数字模型。
结果与结论：实验建立了包括全部骨骼、主要软骨和韧带、皮肤及软组织在内的人足有限元数字模型。利用CT数据及Mimics、Geomagic、Ansys软件可以建立人足全部足骨的三维有限元数字模型，该模型与实际骨骼模型大小、形态一致，并且可以随意旋转，任意角度观看，进行各种测量，可将足部骨骼任意拆分或合并，适合进行生物力学分析。

Abstract:

BACKGROUND: To overcome the disadvantages of traditional mechanical analysis of specimens, and establish the finite element model of realistic foot, are the important basements for the finite element mechanical analysis on foot.
OBJECTIVE: To establish three-dimensional finite element model of foot and lay the foundation for the finite element analysis of normal foot and foot injury.
METHODS: A healthy female volunteer was involved in this study and was detected with spiral CT scanning on the feet. The resulting image was used to reconstruct the three-dimensional model by using Mimics software. Then entity model was generated in Geomagic software. Finally three-dimensional finite element model was established based on the digital main structure in Ansys.
RESULTS AND CONCLUSION: The established finite element digital model of human foot included all bone, cartilage and ligament, skin and soft tissue. The three-dimensional finite element model of human foot was established based on CT data and using Mimics, Geomagic, Ansys softwares. The established model had similar size and shape with skeletal mode, and can rotate freely in any angle for a variety of measurement, the foot bones can be arbitrarily split or merge, which is suitable for biomechanical analysis.
