Abstract

A virtual model of a knee joint with muscles, ligaments and bones has been developed. This model includes realistic 3-D surface deformation and tissue stiffnesses. Tissue and bone deformation (palpation) produces real time force feedback to the user hand wearing a DataGlove and Rutgers Master. Collision detection algorithms determine when and where the virtual hand palpates the surface model. This user interaction with the muscles and bones of a human knee model may be used as a training and planning tool for knee surgery.

摘要

已经开发出一个包含肌肉、韧带和骨骼的膝关节虚拟模型。该模型包括逼真的三维表面变形和组织刚度。组织和骨骼变形（触诊）会向佩戴数据手套和罗格斯主设备的用户手部产生实时力反馈。碰撞检测算法确定虚拟手何时以及在何处触诊表面模型。这种用户与人体膝关节模型的肌肉和骨骼的交互可被用作膝关节手术的训练和规划工具。
