Experimental and theoretical energy and angular dependencies of scattered radiation in the mammography energy range.
Predicted scatter characteristics from a Monte Carlo code have been compared to an experiment for a 4.0-cm-thick acrylic resin (Plexiglas) phantom and 27.3-keV radiation. The results show generally good agreement, except that in the scattered spectra the predictions appear to underestimate the proportion of photons in the low-energy tail of the scattered radiation. The angular dependency of the energy-integrated scattered radiation fluence is in excellent agreement with the predictions.
