摘　　要：目的:研究重建颈椎三维有限元模型。方法:通过CT扫描、Unigraphics V18.0软件进行影像边界记录、定标等方法,按照点、线、面、体的顺序重建三维结构,采用CAD数据处理技术,输入相关的材料特性,验证重建模型的有效性。结果:建立颈椎的三维有限元模型(C3/4),分析结果证明其在仿真分析中是可行的。结论:建立的颈椎三维有限元模型可以模拟生物力学实验。Objective：To propose a method of reconstructing the cervical spine for biomechanical studies. Methods： Reconstructing the skeleton through CT scan, recording the edges of image, calibrating in sequence of point, line, face and solid. Mapped - mesh technique was used to obtain the finite element, adopt finite element commercial software package was used to study the response of the disc model. Results： The model of atlas was reconstructed and verified by he finite element models of cervical spine from C3/4. Conclusion： The finite element models of cervical spine show good response against the experimental data. Which indicates that our model could be used to imitate the biomechanic experiment.
