目的利用上海交通大学生命质量与机械工程研究所自主开发的冷冻切片处理软件CryoSegmentation提取人体骨骼的边缘,利用逆向工程软件Imageware建立骨骼的面模型,在ANSYS中建立人体腰椎的三维有限元模型。方法利用第三军医大学的第一例男性冷冻切片数据进行图像处理,截面轮廓线信息处理。结果准确快速地建立了完全符合人体解剖特征的腰椎三维有限元模型。结论利用该研究所自主开发的冷冻切片软件和一些现有的商用软件可以准确、快速地建立人体腰椎的三维面模型、体模型及有限元模型,为航空、车辆、船舶、生物医学工程等不同的领域进行数值模拟计算和动力学仿真提供完全符合人体解剖学特征的原始模型。
Objective Using CrySegmentation software developed by Institute of Life Quality & Mechanical Engineering to distill the boundary of human bone from Cryo-cadaver, using reverse engineering software Imageware to establish the surface model of lumbar, and then using ANSYS to establish 3D finite element model. Methods Using the first male cryosection data from The Third Military Medical University for Cryosection image processing, and then for the contour line of section information processing. Results 3D finite element model of lumbar with all anatomical characteristic could be established quickly in this way. Conclusion Using CrySegmentation developed by Institute of Life Quality & Mechanical Engineering and some commercial software can precisely and quickly establish surface model, solid model & 3D finite element model of human lumbar to supply the original model based-on anatomy for the purpose of digital simulation and dynamical simulation in the different domain such as aviation, vehicle, shipping, biomedicine engineering, etc.
