Three-dimensional medical imaging display with computer-generated integralphotography

A 3-D display system for medical imaging by computer-generated integral pho tography (IP) has been developed. Real 3-D images are generated from 3-D me dical images and displayed by simple structure. Each point in 3-D space is reconstructed by the convergence of rays from many pixels on the computer d isplay through the lens array. Only the coordinate of the best point is com puted for each pixel on the display, The locations of images projected with in 40 mm from the display were found to be less than 2.0 mm in error. Proje cted images could be observed with motion parallax within 10 degrees from t he front of the display. (C) 2001 Elsevier Science Ltd. All rights reserved .
