Abstract
The effect of patient exposure of X-ray filters made of heavy elements was studied in excretory urography and lumbar spine examinations. Several elements with atomic numbers between 62 and 74 were tested in experiments using radiographic phantoms and in patient studies. A Ho filter reduced skin exposure by more than 50% in excretory urography. Similar results were obtained with Yb and W in lumbar spine studies.This publication has 1 reference indexed in Scilit:
