The Reconstruction of 3D Finite Element Model of Human Cervical Spine Based on Mimics

The paper is aim to establish the 3D finite element model of human cervical spine which is used to the analysis of biomechanics in cervical spine. 84-layer of 0.7-mm-thick Dicom format computerized tomography images of human cervical spine were chosen. With optimization of segmentation, dram and erase in Mimics, the three dimension surface mesh model of human cervical spine was acquired. After being smoothed by the Migics9.9 software the model was imported into the finite element analysis software ANSYS to implement body mesh generation, and then the model was transferred into Mimics with value assignment. The three dimension finite element model was reconstructed in ANSYS. Results demonstrate that with the Mimics software human cervical spine finite element model of realistic appearance and accuracy calculation could be fast and conveniently established. The Mimics software with powerful function ensures the three dimension modeling of medical technology.
