A newly-published study by Dr. Ehsan Samei (Radiology), Dr. Xiang Li (Class 2010), and Dr. Donald Frush (Radiology) offers a new framework which allows physicians and imaging developers to tailor radiation dose to achieve a quantitative target of image quality of pediatric patients. The result is important as body size is a particularly dominant factor for pediatric patients in CT imaging considering the wide range of age group. In the future, this methodology can be used to optimize individual scan parameters and provide for consistent diagnostic performance across the broad range of children body sizes.
