Document Type and Number:
WIPO Patent Application WO/2012/169426
Kind Code:
A1
Abstract:
An x-ray imaging system (10) is provided with: a grid (31) for forming a radiographic image including a period pattern via a transmitting radioactive ray; an x-ray image detector (30) for detecting a radiographic image using a plurality of pixels (40) arranged in a pixel pitch for forming a moiré in a relationship with the period of the period pattern of the radiographic image; and a computing/processing unit (22) for generating a phase contrast image of the imaging subject on the basis of the modulation originating from the imaging subject positioned in the field for irradiation by radioactive rays incident on the grid, and occurring in the moiré of the image obtained by the radioactive ray image detector.
