The subject of this paper is a highly interactive medical training system for arthroscopic surgery; this is based on computer graphics and virtual reality (VR) techniques and offers an alternative to conventional training methods. To provide the virtual environment, a realistic 3D representation of the knee joint is derived from 2D medical image data. The use of tracking techniques guarantees an intuitive handling of the surgical instruments. The system allows navigation via a virtual camera and interaction with the virtual anatomical structures. First approaches for the simulation of tissue deformation caused by collisions with the instruments are implemented. One important advantage over conventional training systems is the possibility of verifying the training progress. Work is in progress on the realization of tactile feedback with the aim of providing a higher degree of interactive realism.
本文的主题是一个用于关节镜手术的高度交互式医学训练系统；该系统基于计算机图形学和虚拟现实（VR）技术，为传统训练方法提供了一种替代方案。为了提供虚拟环境，从二维医学图像数据中获取膝关节的逼真三维表示。跟踪技术的使用保证了手术器械的直观操作。该系统允许通过虚拟相机进行导航，并与虚拟解剖结构进行交互。实现了模拟器械碰撞引起的组织变形的初步方法。与传统训练系统相比，一个重要优势是能够验证训练进展。目前正在开展关于实现触觉反馈的工作，目的是提供更高程度的交互真实感。
