Current practice for imaging surgical breast specimens is a single 2D magnification view on a mammography system,
but 2D imaging overlaps the tissue in different planes causing distortion of lesion margins. Digital breast tomosynthesis
(DBT) could be used as an alternative imaging modality for imaging breast specimens. DBT systems acquire multiple
low dose projection images, over a small angular span, which are then reconstructed into a partial 3D volume. The
reconstructed images can be used to increase visualization of lesion margins and extent of microcalcifications (MCs).
Current commercial DBT systems use a single rotating X-ray source, the movement of which produces motion blur.
Motion blur reduces visualization of small objects such as MCs. MCs, depending on size and structure, can be
implicative of breast cancer. We have developed a stationary DBT (s-DBT) system using a linearly distributed, CNT Xray
source array. S-DBT allows for rapid acquisition of projection images with no image degradation from X-ray source
motion. Full tomosynthesis datasets can be acquired, allowing visualize of both masses and microcalcifications. Here we
report the preliminary results of a reader study comparing breast specimen images from a 2D commercial mammography
system and an s-DBT system. Preliminary results show that s-DBT is capable of producing equivalent image quality to
2D mammography, and in some cases is superior.
