Abstract [en]

Patient dose and image quality were studied in paediatric fluoroscopy. The study consisted of two parts: theoretical calculation of optimal imaging conditions by the Monte Carlo method and clinical measurements of dose rate and SNR2rate at six hospitals. For many imaging tasks the most efficient imaging technique in fluoroscopy is obtained by using high filtration, relatively low X ray tube potential and a fibre-interspaced and -covered grid for all but the smallest patients and X ray field sizes. The clinical measurements supported our theoretical results and revealed a notable variation in image quality and dose rate among the hospitals studied. Notable patient dose rate reduction seems possible in paediatric fluoroscopy by adjusting the equipment to work with more efficient imaging factors and a low image receptor input dose rate.
