Advancements towards the implementation of clinical phase-contrast breast computed tomography at Elettra


   R. Longo et al., ”Advancements toward the implementation of clinical phase-contrast breast computed tomography at Elettra”, J. Synchrotron Rad. 26, 1343-53 (2019); doi.org/10.1107/S1600577519005502


Breast computed tomography (BCT) is an emerging application of X-ray tomography in radiological practice. A few clinical prototypes are under evaluation in hospitals and new systems are under development aiming at improving spatial and contrast resolution and reducing delivered dose. At the same time, synchrotron-radiation phase-contrast mammography has been demonstrated to offer substantial advantages when compared with conventional mammography. At Elettra, the Italian synchrotron radiation facility, a clinical program of phase-contrast BCT based on the free-space propagation approach is under development. In this paper, full-volume breast samples imaged with a beam energy of 32 keV delivering a mean glandular dose of 5 mGy are presented. The whole acquisition setup mimics a clinical study in order to evaluate its feasibility in terms of acquisition time and image quality.
