人体颅脑三维有限元模型构建 总被引:4,自引:1,他引:4
根据人体脑部的螺旋CT扫描图像,利用图形处理,三维重建和有限元网络划分技术,建立了一个基于人体解剖学结构的脑部的三维有限元模型。用非规则形体、有限元软件Ansys划分网格。此模型包括大脑左右半球,小脑,脑干,大脑镰,小脑幕,网格细化到平均尺寸6mm,此模型以精确CT数据为依据,为宇航、交通事故、司法鉴定创伤判断、临床治疗提供可用颅脑有限元模型. 相似文献

1 Introduction With the development and advancement of society and computer technology, finite- element method (FEM) has becomes more and more popular in solving problems in projects. In the field of biomechanics, FEM is also an important method, which is effective, accurate, low- lost and applied. We can use FEM to build up the model of complicated geometrical object, to calculate the whole and partial stress and displacement and also the regular- ities of distributions, to compare the re… 相似文献
