We are interested in the application of computer animation to surgery. Our current project, a navigation and visualization tool for knee arthroscopy, relies on real-time computer graphics and the human interface technologies associated with virtual reality. We believe that this new combination of techniques will lead to improved surgical outcomes and decreased health care costs. To meet these expectations in the medical field, the system must be safe, usable, and cost-effective. In this paper, we outline some of the most important hardware and software specifications in the areas of video input and output, spatial tracking, stereoscopic displays, computer graphics models and libraries, mass storage and network interfaces, and operating systems. Since this is a fairly new combination of technologies and a new application, our justification for our specifications are drawn from the current generation of surgical technology and by analogy to other fields where virtual reality technology has been more extensively applied and studied.
