Description of activity and work performed
The aim of this work is to determine possible radiation exposure of the female breast caused by abdominal CT compared to X-ray mammography. Furthermore our goal is to show ways to decrease respective dose levels. To reach these objectives special PMMA breast phantoms for adaption on a Rando-Alderson-Phantom were manufactured. With those PMMA phantoms and LiF-rods thermoluminescent dosimeters, dose measurements of the breast were performed. Three different standardized routine examination protocols, depending on different clinical questions, for abdomen-pelvis, liver and urinary tract CT examinations were used, respectively. Finally, our results were compared to the Austrian diagnostic reference level (DRL) for the mean glandular breast dose.
