Real Time Computer Simulation of Human Soft Organ Deformation for Computer Assisted Surgery

本研究拟开发计算框架，实现手术过程中软器官（脑、肝、肾、前列腺等）变形的实时计算。将使用完全非线性的材料模型和几何非线性的有限元公式。该项目开发的基础技术：物理（或机械）逼真建模和软器官变形的实时计算机模拟，将在计算机辅助手术的许多领域得到应用，例如术中，实时非刚性注册和具有力和触觉反馈的虚拟现实外科医生培训和操作计划系统。

The proposed research will develop computational framework, which will allow calculation of soft organ (brain, liver, kidney, prostate, etc.) deformation during surgical operations in real time. Fully non-linear material models and geometrically non-linear finite element formulation will be used. The fundamental technology developed within this project: physically (or mechanically) realistic modelling and real time computer simulation of soft organ deformation, will have applications in many areas of computer assisted surgery, such as intra-operative, real time non-rigid registration and virtual reality surgeon training and operation planning systems with force and tactile feedback.
