摘要
介绍了一种应用虚拟现实技术实现消化道内窥镜训练功能的系统.主要讨论了通过计算机三维可视技术,对医学断层影像重建得到三维训练模型;并讲解系统外设实现操作量采集和力反馈的工作原理,以及系统仿真软件采用的质点-弹簧/阻尼物理仿真模型.学员可在这一具有虚拟场景和真实力感相结合的训练环境中反复训练,从而不断提高业务操作水平.
The paper introduces a virtual endoscopy training system which has applied the technology of VR（Virtual Reality ）. The paper discusses how to reconstruct the 3D model of alimentary canal from many medical tomographic images using the computer 3D visualization technology, explains the work principle of its operation signal gathering devices and feedback force controlling devices, and describes the mass-spring/damper simulation model used in the software emulation. The trainee can improve their performance by repeatedly using the system, while furnishing not only virtual scenes but also real force feeling.
