摘要: OBJECTIVE. The purpose of this study was to estimate the effective doses received by pediatric patients during interventional radiology procedures and present those in “look-up tables” standardized according minute fluoroscopy frame digital subtraction angiography (DSA).MATERIALS AND METHODS. Organ were measured with metal oxide semiconductor field effect transistor (MOSFET) dosimeters inserted within three anthropomorphic phantoms, representing children at ages 1, 5, 10 years, locations corresponding radiosensitive organs. phantoms exposed mock head, chest, abdomen using posteroanterior lateral geometries, varying magnification, or DSA exposures. Effective calculated from organ recorded MOSFET are presented look-up tables different age groups.RESULTS. largest dose burden for posteroanterio...
