ABSTRACT:
Apparatus and a method for making an X-ray photograph of an object wherein the photograph, when viewed through a lenticular screen or other similar device, will provide a three-dimensional picture of the object and the interior parts thereof. The method is carried out by successively directing the X-ray beams from a conventional X-ray tube through the object, then through a parallax grating, and finally onto the film. The grating is mounted on the film support member and the object and film support member together are translated in parallel paths laterally with respect to the beam path at different speeds sufficient to maintain the film and object in congruent alignment with the X-ray tube. Since the position of the grating is fixed relative to the film, the grating moves slightly out of congruency causing the beam passing through the grating to slightly scan the film during the traverse. During traverse, the angle at which the object is exposed to radiation from the X-ray tube gradually changes. The resulting image on the film is a series of side-by-side variable aspect views or images of the object, corresponding in number to the number of slits in the grating, which can be viewed in three-dimension with the lenticular screen. Accurate measurements of the depth, size and motion of one or more internal parts of the object can be determined from measurements of those parts when viewed through the lenticular screen.
