Title
(EN) HYBRID SLOT-SCANNING GRATING-BASED DIFFERENTIAL PHASE CONTRAST IMAGING SYSTEM FOR MEDICAL RADIOGRAPHIC IMAGING
Abstract
(EN)

Embodiments of methods and apparatus are disclosed for obtaining a phase-contrast digital mammography system and methods for same that can include an x-ray source for radiographic imaging; a beam shaping assembly including a filter or a tunable monochromator, a collimator, a source grating, an x-ray grating interferometer including a phase grating, and an analyzer grating; and an x-ray detector; where the source grating, the phase grating, and the analyzer grating are aligned in such a way that the grating bars of these gratings are parallel to each other.
