摘要
目的针对数字化虚拟中国男性一号的膝关节断面切片图像,建立可供有限元结构仿真分析的膝关节三维模型。方法将中国数字化虚拟人体男性一号膝关节部位的薄层切片数码图像输入PC机,经过分割、配准等处理后,利用三维重建软件Mimics建立三维图像,然后通过自由造型系统进行表面光滑处理,再对表面图像矢量化,存储为有限元仿真分析可以接受的格式。结果建立了人体膝关节的三维计算机模型,并转换为IGES格式,可以提供膝关节的有限元生物力学仿真分析。结论利用Mimics重建后的三维计算机模型,可经自由造型系统FreeForm plus转换后应用于有限元仿真分析。
To provide a three-dimensional (3D) model of the knee joint of digitized Virtual Chinese Male No.1 for finite element simulation, the digitized image data of the serial sections of the virtual human knee joint were imported to a computer for 3D reconstruction using Mimics software after image segmentation and registration. Surface smoothing of the reconstructed model was performed with FreeForm system and transformation to IGES format executed. Following these procedures, the 3D model of IGES format of knee point was reconstructed, which can be used for finite element simulation.
