ABSTRACT:
A method of taking an X-ray photograph by using a cassette containing an X-ray film and a stimulable phosphor sheet maintained in close contact with each other in a light shielding case. When the cassette is exposed to X-rays through an object, an X-ray transmission image of the object is recorded on the 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 a photographic latent image of the X-ray transmission image of the object on the X-ray film. The X-ray film may be provided with an emulsion layer only on the side facing the stimulable phosphor sheet, or may be provided with emulsion layers on both sides. In the latter case, an intensifying screen may be positioned on the side of the X-ray film opposite to the stimulable phosphor sheet.
