Effects of x‐ray scattering on full‐field digital mammography are analyzed with the scattering model of Seibert and Boone [Med. Phys. 15 , 567–575 (1988)]. A new method is introduced for the estimation of model parameters from measurements. It is shown that with breasts thinner than a certain threshold, removing the anti‐scatter grid leads to an improved contrast‐to‐noise ratio with a smaller patient dose. A fast approximate algorithm is presented for determining the scattered field in a gridless digital mammogram.
