ABSTRACT:
An X-ray film holder which permits optional fluoroscopic or radiographic examination of a patient has a number of screen foils disposed in a film conveying track wherein X-ray film is provided between a supply magazine and a take-up magazine. The film changer is disposed between the patient and an X-ray image intensifier, the changer and the intensifier having the same image axis. The film changer has a conveyor unit for moving the screen foils into place in front of the image intensifier and for automatically opening overlapping flaps of the screen to permit an X-ray film sheet to be moved therebetween. As needed, the screen foils can be conveyed in an opposite direction to a storage area to permit radiation to pass unobstructed to the image intensifier for fluoroscopic examination of the patient.
