摘要：
The invention relates to an X-ray differential phase-contrast imaging system which has three circular gratings. The circular gratings are aligned with the optical axis of the radiation beam and a phase stepping is performed along the optical axis with the focal spot, the phase grating and/or the absorber grating. The signal measured is the phase-gradient in radial direction away from the optical axis.
