背景：骨盆是人体骨骼中形态及结构最复杂的部分，许多学者一直致力于其生物力学的研究。由于骨盆形状极其不规则，所附着肌肉及韧带解剖结构复杂，建立精确的包含主要肌肉及人韧带的骨盆有限元模型十分困难。 　　目的：建立正常成年人骨盆的三维有限元模型，为后续骨盆的生物力学分析提供数字模型。 　　方法：采集健康成年男性志愿者的骨盆CT数据，将DICOM格式的CT图像导入医学影像三维重建软件Mimics 10.0进行图像的分割及三维重建，将导出文件导入逆向工程软件Geomagic studio 11中对图像进行曲面化处理，建立曲面模型，使其更加光顺，将生成的曲面模型导入有限元分析软件Ansys 14.0中进行有限元网格划分。 　　结果与结论：建立了正常成年人骨盆的三维有限元模型，总单元数为818294个，总节点数为149290个。课题基于健康成年男性志愿者的骨盆 CT 图像建立骨盆有限元模型，所得的模型精确度高、逼真、具有良好的解剖及几何相似性，可为下一步骨盆的生物力学分析提供基础。

BACKGROUND:Pelvis is the most complicated structure of human body, and many scholars have devoted themselves to its biomechanical study. However, it is difficult to construct the pelvic finite element model containing main muscles and ligaments, as a result of its irregular shape and complicated structure. OBJECTIVE:To establish a normal human pelvis three-dimensional finite element model and provide digital model for the subsequent biomechanics analysis of pelvis. METHODPelvic CT images of healthy male volunteers were stored in DICOM format and then put into Mimics 10.01 software for three-dimensional medical image reconstruction. The files were imported into reverse engineering software Geomagic studio 11 for surface processing and establishing surface model;then the surface model was introduced into finite element analysis software Ansys 14.0 for finite element meshing. RESULTS AND CONCLUSION:A normal adult pelvis three-dimensional finite element model was developed, including 818 294 units and 149 290 nodes. Based on the CT images, we established pelvic finite element model, which have good accuracy, anatomical and geometric similarity, and could provide the basis for subsequent biomechanics analysis of pelvis.
