软组织模型的变形计算是虚拟手术中的一个重要组成部分，尽管大量的研究一直致力于模拟软组织的形变，软组织变形的建模仍然是一个具有挑战性的问题。从仿真实时性的角度，提出了一种基于混合有限元模型的软组织模型解决方案。实验仿真表明该方案提高了计算效率，节省了大量内存，实验仿真表明达到了实时性仿真水平。%The soft-tissue-deformation pIays an important roIe in the virtuaI surgery.AIthough amount of research efforts have been dedicated to simuIating the deformation of soft tissues,modeIing of soft tissue deformation is stiI a chaI enging probIem.From the viewpoint of reaI-time simuIation,this paper presents a noveI deformation modeIing scheme based on a hybrid condensed finite eIement modeI for virtuaI soft tissue.This scheme improves the computationaI efficiency and saves a great Iot of memory.The experimentaI simuIation show that the system achieve the IeveI of reaI-time interaction.
