Title:
RADIOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/050005
Kind Code:
A1
Abstract:
The invention shortens the time from imaging until the radiographic image is generated by image processing. First and second absorption gratings are disposed between an X-ray source and an X-ray image detector (FPD). Images are taken at each position while intermittently moving the second absorption grating relative to the first absorption grating and the M number of images are stored in the memory. A communication unit reads out sequentially and transfers, to a phase differential image-generating unit, the M number of pixel data pertaining to the same pixel from the M number of images. The phase differential image-generating unit calculates a phase differential value each time it receives all of the multiple pixel data pertaining to the same pixel. A phase contrast image-generating unit performs integration each time a phase differential value is generated by the phase differential image-generating unit. An image having said integrated values as the pixel values is displayed.
