Abstract

The major goal of this research is to develop a networked collaborative surgical system for tele-immersive consultation, surgical pre-planning, implant design, post operative evaluation and education. Tele-immersion enables users in different locations to collaborate in a shared, virtual, or simulated environment as if they are in the same room. The process of implant design begins with CT data of the patient and the Personal Augmented Reality Immersive System (PARISTM). The implant is designed by medical professionals in tele-immersive collaboration. In the PARIS augmented reality system the user's hands and the virtual images appear superimposed in the same volume so the user can see what he is doing. A haptic device supplies the sense of touch by applying forces to a stylus that the medical modeler uses to form the implant. After the virtual model of the implant is designed, the data is sent via network to a stereolithography rapid prototyping system that creates the physical implant model. After implant surgery, the patient undergoes a postoperative CT scan and results are evaluated and reviewed over the tele-immersive consultation system.
