In the x-ray region above several keV, phase-contrast is much higher than absorption contrast. We have been developing a differential phase-contrast microscope by using an x-ray microscope with a zone plate and a Foucault knife-edge scanning filter [1]. A relatively quantitative differential phase image can be obtained by scanning a knife edge at the back focal plane of the objective zone plate. Using this microscope, differential phase-contrast imaging and phase tomography of biological samples could be successfully demonstrated [2].
