摘要
软组织仿真研究是利用计算机技术对真实软组织进行模拟以便研究,为医学工作者提供辅助和帮助科研工作者更好地进行虚拟手术。这方面的研究在国外已经较为普及,在国内尚处于起步阶段。软组织仿真算法已有多种成熟模型,其中较为代表性的有弹簧振子模型(MSS)和有限元模型(FEM)。在参阅了前人的研究基础上,选取了弹簧振子模型作为软组织仿真的物理形变模型,并对仿真算法进行编码和仿真实验,进而对实验效果进行分析,并提出改进之处。实验发现基于弹簧振子模型的软组织较好地实现了形变仿真的效果。
Simulation of soft tissue uses computer science and technology to modeling for the soft tissue which will help doctors and scientists to research.It has been researching widely,but it is a start in China.There are many mature models for simulation of soft tissue,among them,MSS and FEM are two typical models.Selects Mass-Spring-Model as the physical model for soft tissue after referring to the previous research achievement.Then,it does experiments on the model and put forward the improvement for the model after analyzing the effect of deformation.It does well in simulating the deformation based on the MSS.
