Virtual environments such as the CAVE and the ImmersaDesk, which are based on graphics supercomputers or workstations, are large and expensive. Most physicians have no access to such systems. The recent development of small Linux personal computers and high-performance graphics cards has afforded opportunities to implement applications formerly run on graphics supercomputers. Using PC hardware and other affordable devices, a VR system has been developed which can sit on a physician's desktop or be installed in a conference room. Affordable PC-based VR systems are comparable in performance with expensive VR systems formerly based on graphics supercomputers. Such VR systems can now be accessible to most physicians. The lower cost and smaller size of this system greatly expands the range of uses of VR technology in medicine.
基于图形超级计算机或工作站的虚拟环境，如CAVE和沉浸式桌面，规模大且成本高。大多数医生无法使用此类系统。小型Linux个人计算机和高性能图形卡的最新发展为实现以前在图形超级计算机上运行的应用程序提供了机会。利用个人电脑硬件和其他价格实惠的设备，开发出了一种虚拟现实（VR）系统，它可以放置在医生的桌面上，也可以安装在会议室里。价格实惠的基于个人电脑的VR系统在性能上可与以前基于图形超级计算机的昂贵VR系统相媲美。现在大多数医生都可以使用此类VR系统。该系统较低的成本和较小的尺寸极大地扩展了VR技术在医学领域的应用范围。
