This report documents the state of development of enhanced and virtual reality-based systems in medicine. Virtual reality systems seek to simulate a surgical procedure in a computer-generated world in order to improve training. Enhanced reality systems seek to augment or enhance reality by providing improved imaging alternatives for specific patient data. Virtual reality represents a paradigm shift in the way we teach and evaluate the skills of medical personnel. Driving the development of virtual reality-based simulators is laparoscopic abdominal surgery, where there is a perceived need for better training techniques; within a year, systems will be fielded for second-year residency students. Further refinements over perhaps the next five years should allow surgeons to evaluate and practice new techniques in a simulator before using them on patients. Technical developments are rapidly improving the realism of these machines to an amazing degree, as well as bringing the price down to affordable levels. In the next five years, many new anatomical models, procedures, and skills are likely to become available on simulators. Enhanced reality systems are generally being developed to improve visualization of specific patient data. Three-dimensional (3-D) stereovision systems for endoscopic applications, head-mounted displays, and stereotactic image navigation systems are being fielded now, with neurosurgery and laparoscopic surgery being major driving influences. Over perhaps the next five years, enhanced and virtual reality systems are likely to merge. This will permit patient-specific images to be used on virtual reality simulators or computer-generated landscapes to be input into surgical visualization instruments. Percolating all around these activities are developments in robotics and telesurgery. An advanced information infrastructure eventually will permit remote physicians to share video, audio, medical records, and imaging data with local physicians in real time. Surgical robots are likely to be deployed for specific tasks in the operating room (OR) and to support telesurgery applications. Technical developments in robotics and motion control are key components of many virtual reality systems. Since almost all of the virtual reality and enhanced reality systems will be digitally based, they are also capable of being put "on-line" for tele-training, consulting, and even surgery. Advancements in virtual and enhanced reality systems will be driven in part by consumer applications of this technology. Many of the companies that will supply systems for medical applications are also working on commercial products. A big consumer hit can benefit the entire industry by increasing volumes and bringing down costs.(ABSTRACT TRUNCATED AT 400 WORDS)
