Abstract
An X-ray imaging system which enables recording of an X-ray image of an object at a desired time without substantial delay while fluoroscopically observing the X-ray image with the eye, and in which the filament current of the X-ray tube is kept at a constant level at all times, and the tube voltage is supplied in synchronism with the vertical scanning of a TV camera in the form of pulses, the width of which is changed depending upon whether the X-ray image is fluoroscopically observed with the eye or a picture thereof is radiographically recorded.
