Stereoscopic images using a viewing grid

Stereoscopic images are viewed using a viewing grid having alternating light absorbing and light transmitting lines and not requiring a lenticular viewing screen. In one embodiment an X-ray source, a table or cradle disposed beneath the X-ray source for securing an image subject such as a patient, and a recording medium cassette disposed beneath the table or cradle are used. The cassette includes a film comprising a base, an emulsion on a first side of the base and a viewing grid on an opposite second side of the base, an image intensifying screen for exposing the emulsion films for recording an image, and a recording grid located between the screen and the emulsion side of the film, and fixed in position relative to the image intensifying screen for masking a plurality of strips of predetermined width, of the emulsion film. During exposure, relative movement between the cradle and cassette is maintained so as to capture various views of the image subject on the emulsion film. Where tomographic images are recorded, frontal and rear view stereoscopic images can be visualized on opposite sides of the film, respectively. The viewing grid may be formed on a cathode ray tube or liquid crystal diode screen.
