Abstract: Plural transducer elements, comprising a single transducer, are associated with an X-ray tube to produce an output which varies with average intensity of X-ray radiation. The transducer element outputs are summed, averaged and amplified, and are corrected for factors common to both radioscopy and photography, then fed, through a selector switch, either to a dose velocity controlling device which maintains radiation intensity at a desired level for radioscopy, or to an exposure controlling device which times photographic exposures.
