Abstract

Theoretical and experimental investigations of a method for direct recording and reconstruction of 3-D x-ray images are described. When recording, an x-ray source is placed at discrete positions, and an x-ray grid is fixed on the x-ray plate. When reconstructing, a lenticular sheet matched with the grid is overlayed on the developed plate, and a parallax–panoramagram type 3-D image is seen with the naked eye. Using a small x-ray source designed for use in dental clinics and an x-ray grid matched with the lenticular sheet, 3-D x-ray images having a 0.001-rad resolvable angle and a 0.02-rad flipping angle are directly recognized with clear parallax.
