Noise and dose levels in paediatric CT
Jenny Oduko
Bristol
Abstract
An audit of paediatric CT examinations revealed that a wide range of parameters were being used, especially by on-call radiographers.
A set of simple water-filled phantoms of different sizes were used to make noise measurements, and the results were used to suggest exposure parameters for children of different body sizes (making use of the anthropometric data in NRPB Report R318, 'Reference Doses and Patient Size in Paediatric Radiology').
