摘要
有限元法是指通过对医学组织图像(CT)的三维重建,将其转换为具有直观立体效果的三维有限元模型,通过对有限元模型进行材料选取、施加载荷、求解等操作,得到有限元组织模型的力学特性,从而更清楚的观察组织的应力、应变过程。该技术可以更好地处理复杂的生物力学问题而被广泛应用于生物医学领域,目前把有限元法和动物组织结合起来的研究逐渐成为了热点。论文对有限元法在动物组织模型构建上的研究前景和应用优势进行综述,为动物组织模型构建方面的研究提供新的方法和思路。
Finite element method refers to the three-dimensional reconstruction of medical tissue image(CT),which is converted into a three-dimensional finite element model with intuitive stereoscopic effect.By selecting materials,applying loads,solving problems and other operations on the finite element model,the mechanical properties of finite element model of organization the stress and strain process of the tissue can be observed more clearly.This technique has been widely used in biomedical field because it can better deal with complex biomechanical problems.At present,the research of combining the finite element method with animals has gradually become a hotspot.Therefore,this paper summarizes the research prospect and application advantages of finite element method in the construction of animal tissue model,and provides new methods and ideas for the research of animal tissue model construction.
