Factors affecting radiation exposure and radiographic image contrast in urology.
An evaluation of certain radiographic factors affecting patient exposure during urography is made. Factors considered include selection of tube kilovoltage, total beam filtration and film-screen combination. The effect on image quality is also considered. Experimental results suggest specific actions which would result in decreased patient exposure without compromising quality of the examination.
