Abstract

Directly reading 228-layer 0.75-mm-thick consecutive CT Dicom format images of human body thoracolumbar into the Mimics, and then the three-dimensional geometric surface mesh model was acquired after the redundancy data was cleaned. Then the surface mesh model could be introduced into Ansys, and volumetric mesh in Ansys. Then the volumetric mesh was introduced into mimics to assign material, and the three-dimension finite element model was generated in Ansys. The triangles with low quality could be repaired in the mimics. This method is rapid and high accuracy. The three-dimension finite element model is very helpful to study biomechanics.
