(a) Photograph showing the FFDM imaging system used in this evaluation (Siemens Mammomat Novation^DR, Siemens Medical Systems) and the phantom configuration employed for evaluation of the FOM. Three breast compositions (100% adipose, 50% adipose/50% glandular, and 100% glandular) were imaged simultaneously in thicknesses of 2, 4, 6, and 8 cm. A large compression paddle was used to support petri dishes containing oil and simulated mass and calcium inclusions [see Fig. 1b]. (b) Overhead schematic of the relative position of mass and calcium simulated lesions with respect to the breast phantom.
