X-Ray Phase-Contrast Imaging with Three 2D Gratings

X-Ray Phase-Contrast Imaging with Three 2D Gratings

X-ray imaging is of paramount importance for clinical and preclinical imaging but it is fundamentally restricted by the attenuation-based contrast mechanism, which has remained essentially the same since Roentgen's discovery a century ago. Recently, based on the Talbot effect, groundbreaking w...
