摘　　要：针对目前通过医学成像技术获得人体器官序列图像来提取相关人体器官结构参数，判断人体器官的功能的热点问题，提出了一种基于有限元法Delaunay四面体网格的建模方法，利用有限元与生物力学原理构建人体器官表面重建的有限元方程，以满足单元的应力矢量及单元节点位移矢量计算的需要，为模拟重建人体器官运动奠定基础。Focused on judgment the function of the human organs through medical imaging technology to obtain the human organs sequence of images to extract relevant parameters of human organs structure. A new method based on the Delaunay tetrahedral mesh of the finite element is presented in this paper. The finite element equation of the human organs surface reconstruction is by means of biomechanics principle and finite element, which satisfy the needs of calculating cell＇s stress and displacement. The proposed method provides the foundation for reconstructing of human organs movement.
