Abstract

We present a new mammography phantom made of hydroxyapatite crystals with different sizes and shapes, to emulate anthropomorphic microcalcifications, which we locate at different depths of a PMMA embedding material. The aim of the phantom presented is to address some issues of the standard commercial ones that are being used for comparing 3D vs 2D mammography systems. We present X-ray images, taken under the same conditions, for both a commercial phantom and the new proposed phantom. We compare signal to noise ratios (SNR) obtained for both cases. This phantom has been constructed to be easily assembled within different configurations to emulate modified features that might be of medical interest.
