Abstract
An X-ray photographing apparatus includes an X-ray tube for generating an X-ray pulse beam, a shutter for shutting off the X-ray pulse beam which is emitted from the X-ray tube, and a shutter controller for permitting the X-ray pulse beam shut off by the shutter to be passed therethrough when the intensity of the X-ray pulse beam from the X-ray tube reaches a substantially constant level. The apparatus permits the subject to be exposed at all times with a stabilized intensity of X-ray beam.
