Imaging plate cassette for extended X-ray photographs

摘要

A method of taking an extended X-ray photograph by using an film cassette devised to contain a longer X-ray film such that a longer complete image of a subject may be rendered such that no diagnostic information is lost in examinations of scoliosis or the long bones of the body. When the cassette is exposed to X-rays through an object, an X-ray transmission image of the object is recorded on a stimulable phosphor sheet and, at the same time, the X-ray film is exposed to light instantaneously emitted from the stimulable phosphor sheet upon exposure to X-rays to record an extended photographic latent image of the X-ray transmission image of the object on the X-ray film.
