[Effect of x-ray hardness on the informativeness of fluorograms].
The power unit model URP-phi built on a single-phase generator supplied by a full-wave rectification circuitry along with an X-ray image intensifier model URI-230/150 enable the fluorography under radioscopy control. During X-ray examinations it automatically selects anode voltage of the X-ray tube depending on both the density of the subject under study and the examining angle. Specified in the URP-phi the anode voltage-current relationship provides higher X-ray intensity attenuation through the subject for anode current 3 mA compared to the current 1 mA, the detection of low contrast abnormalities being virtually the same for the fluorograms of the stepped phantoms.
