| 摘 要： | 为建立老年健康女性盆底肛提肌有限元模型(FEM),对一老年未孕女性健康志愿者进行骨盆CT及MRI薄层扫描,获得其骨盆及盆底肛提肌的原始图像数据,随后应用Mimics12.0及Geomagic9.0图像处理软件将骨盆诸骨、肛提肌及其相关肌肉进行三维重建和网格优化,在Ansys11.0软件平台上构建骨盆与肛提肌群的肌骨系统FEM,并最终获得精确的老年健康女性盆底肛提肌及骨盆的FEM。结果表明:采用CT及MRI薄层扫描数据建立的FEM真实可靠,能逼真反应盆底肛提肌的空间立体解剖关系,避免了已往依赖于尸体标本解剖获得模型的缺点,所获得的模型数据更加接近于活体解剖,有利于后期的有限元分析。

| Abstract: | This paper is to establish a three-dimensional finite element model(3D-FEM) of pelvic floor levator ani muscles in an old healthy women.We acquired the image data of the pelvic bones and pelvic floor muscles from CT and MRI scanning in a non-pregnant old healthy female volunteers.The 3-D reconstruction and mesh optimization of the whole pelvic bones and muscles with application of image processing software Mimics12.0 and Geomagic9.0 were obtained.Then we built the 3D-FEM of the musculoskeletal system of the... |
