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.

拟议的研究将开发计算框架，这将允许计算软器官（大脑，肝脏，肾脏，前列腺等）。真实的时间的外科手术期间的变形。将使用完全非线性材料模型和几何非线性有限元公式。该项目中开发的基本技术：软器官变形的物理（或机械）逼真建模和真实的时间计算机模拟，将应用于计算机辅助手术的许多领域，如术中、真实的时间非刚性配准和虚拟现实外科医生培训以及具有力和触觉反馈的手术规划系统。
