Abstract

To evaluate performance (image signal to noise ratio) of a digital mammographic system working in 2D planar versus tomosynthesis modality, a contrast detail phantom was developed embedding 1 cm plexyglas, including 49 holes of different diameter and depth, between two layers containing a breast simulating material. The acquisition protocol included 15 low dose projections (reconstructed 1mm-thick slices) and a 2D view. Using an automatic software analysis tool, the signal difference to noise ratio (SDNR) was evaluated. SDNR in the DBT images was about a factor two higher than with FFDM (P
