Abstract
Low contrast-detail phantoms of glandularity 30, 50 and 70%, and thickness 3, 5, and 7cm were imaged. Screen-film (SF), imaging plate (CR), and full-field digital mammography (FFDM) systems were studied. Images were acquired for a range of anode/filter/tube potential/dose (AGD) combinations. The number of perceivable objects (score) was recorded and AGD determined. For FFDM, image scores similar to those with SF can be achieved at 20–60% of the SF dose. The largest dose reduction potential was found for the thickest phantoms and highest glandularity. With CR, a dose reduction of 10–20% was found, the largest reduction appearing for the thinnest phantom thickness.
