摘　　要：针刺人体软组织是医疗诊断中比较普遍使用的治疗手段,然而细微的针刺操作对医生的能力提出较高的要求。医生可采用虚拟现实技术来进行大量的训练,获得宝贵的经验。虚拟针刺过程中的软组织变形是重要研究内容。文章采用有限元方法建立软组织模型,使用GPU加速仿真的方法,实现针刺软组织的仿真。实验结果表明,软组织模型在针刺作用下,能产生局部的、小区域的变形。Needle insertion of human soft tissue is a traditional treatment;however subtle manipulation of needle insertion demands more for doctors.Doctors can use virtual reality technology for extensive training,in order to get the valuable experience.The deformation of soft tissues is a vital research in the needle insertion.In this paper,the model for soft tissue is established with FEM,and the simulation is accelerated by GPU to realize the simulation of virtual needle insertion of body's soft tissue.The result shows that during the process of needle insertion,soft tissue can make local and small area deformation.
