Concurrent three-dimensional endoscopy with head-mounted video display: a preliminary laboratory experience

Head-mounted virtual display systems have allowed improved visualization and operative efficiency during endoscopic procedures. Despite the improvement in display systems and development of new endoscopic tools, endoscopy is a technique which is known for its steep learning curve and difficulty when used in regions where local anatomy is distorted by disease processes. We describe a stereoscopic endoscope system mated to a head-mounted display which allows for more rapid appreciation of three dimensional anatomy as seen through the endoscope.
