ABSTRACT:
An X-ray image from an image intensifier is projected on an image pickup surface of a television camera. The television camera converts the X-ray image into a video signal. The video signal is reproduced as an X-ray image on a monitor television. In ordinary fluoroscopic photographing, the video signal is blanked, and supplied to the monitor television. In cine-photographing, on the other hand, the X-ray image, constricted by an X-ray stop, is projected on the television camera, a scanning region substantially identical with the constricted X-ray image is scanned, and a video signal corresponding to such X-ray image is supplied to the monitor television without being blanked.
