Abstract

Abstract Permanent identification of patient information including facility where x-rays are performed, the facilities' address, the patients' name, the number of the x-ray and the date of the x-ray, are imprinted on x-ray film using a flash marking system and a special four-sided flash card. The four-sided flash card is so designed that a single card may be used to imprint information regarding four patients. The information written on the flash card with a dark graphite pencil is thus transferred to the x-ray film by means of a light flash which passes thru the card in the area imprinted with patient information and on to the unexposed x-ray film which overlays the imprinted information on the card. Thus the x-ray film is permanently inscribed with the foregoing information.
