title: A comparison of fluoroscopically controlled patient positioning and conventional positioning, including comparative dosimetry.
abstract: The size of the area of exposure on the skin during excretory urography was determined by either technician-controlled fluoroscopy or conventional assessment in 2 comparable groups of patients. The mean skin exposure to radiation per patient was the same in each group. The time required for a urogram was 10% less when fluoroscopy was employed. Since accurate, tightly shuttered exposure areas improve radiographic quality, fluoroscopically controlled determination of patient positioning is justified.
