Popis:	This paper reports on a further development of an image simulation chain, and in particular, the inclusion of contrast degradation across an image using scatter to primary ratios calculated using Monte Carlo simulation The Monte Carlo technique, using the Geant4 toolkit, has been implemented to model the scatter conditions when imaging the CDMAM phantom with commercial digital mammography Observed differences between linear and cellular anti scatter grid are presented and discussed These results support previous assumptions taken by Yip et al.[1].
