Virtual Medical Training System

Physical Optics Corporation proposes to develop a high resolution, high quality image generator and display for combat trauma surgery training. The Virtual Medical Training (VMT) system, based on our patented 3-D display technology, includes a 3-D display(horizontal geometry without headwear) for the trainee and instructor linked to a virtual human database with an injury generator and a haptic feedback device. The Holographic Horizontal (H2) screen and 3-D projection display 3-D objects floating over thescreen surface where each viewer can see the same object from his or her own perspective. The 3-D effect is achieved by projecting slightly different views of the object in front of each viewer at a high refresh rate. The viewer can move freely withinthe volumetric 3-D zone that extends out from the edge of the screen. The essence of the system is a special type of screen that converges the light into a narrow beam slice of about 1 degree (2 mm wide) representing a single view of the object that istime multiplexed (shifted in front of the viewer), producing a multiplicity of views. The narrow beam position is synchronized with the rendering of the corresponding view, producing a true 3-D effect.The major benefits are efficient training of medicalpersonnel. The system can also be used in television, robotics, and teleoperation. Additional applications include video games and CAD/CAM simulation.
