腰椎L3-L5三维有限元模型的有效性验证**☆OACSCDCSTPCD
Validation and verification of L3-L5 lumbar three-dimensional finite element model
背景：建立精确的有限元模型是对脊柱进行有限元力学分析的重要基础，精确的腰椎有限元模型报道较少。目的：采用正常人腰椎CT资料建立L3-L5三维有限元模型，并进行有效性验证。<br> 方法：健康男性志愿者，39岁，身高175 cm，体质量65 kg，采用16排螺旋CT机对L3-L5节段进行扫描，得到1.25 mm层厚的 CT图片共101张，Geomagic9.0软件下建立几何实体模型，然后确定单元类型、划分有限元网格，建立有限元模型…查看全部>>
BACKGROUND:Creation of a precise finite element model is an important basis for the finite element mechanical analysis of the spine. The reports on the precise finite element model are less. <br> OBJECTIVE:To create L 3-L 5 lumbar three-dimensional finite element model and validate this model with normal CT data. <br> METHODS:A 39-year-old male healthy volunteer with the height of 175 cm and weighted 65 kg was selected, then the L 3-L 5 lumbar …查看全部>>
