Abstract
In a national breast screening program using analog mammography systems, the dose to a 45 mm phantom was routinely calculated at annual physics surveys. This test procedure was retained through the gradual transition to digital mammography. Here the phantom doses recorded for 50 analog mammography systems, and 24 (2007) and 35 (2008/2009) digital systems are compared. The phantom doses for the digital systems were found to be statistically significantly lower than the doses for the analog systems. The digital doses were essentially unchanged from 2007 to 2008/2009.
