Computed tomographic scanning in children: comparison of radiation dose and resolving power of commercial CT scanners

AJR Am J Roentgenol. 1978 Jul;131(1):95-101. doi: 10.2214/ajr.131.1.95.


Surface and internal radiation doses for abdominal computed tomography (CT) of children were determined using child-sized phantoms and seven models of CT body scanners. Resolving power of each scanner was determined simultaneously with the radiation dose determination. The average surface skin dose for a complete CT body examination ranged from 0.39 to 5.60 rad, varying with patient size and model of CT scanner employed. A high contrast (12%) resolving power phantom of water-filled holes in acrylic showed a range of 1.75--2.25 mm.
