Abstract

We have performed spectral analysis of simulated tomosynthesis projections generated using an anthropomorphic software breast phantom. Twenty phantoms were generated: ten 450 ml phantoms with 40% glandular fraction and ten 1500 ml phantoms with 20% glandular fraction. Simulated mammographic compression and acquisition was performed using monoenergetic ray-tracing. ROIs were extracted and the modulus-squared 2D FFT was applied to each ROI to obtain periodograms. Radially-averaged periodograms were compared between phantom and clinical images. We observed a good agreement between the spectral power law exponents (β) calculated from phantom projections and clinical images.
