Title:
RADIOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/169427
Kind Code:
A1
Abstract:
An x-ray imaging system (10) provided with an imaging unit (12) and a computing/processing unit (22), wherein: the imaging unit (12) has grids (31, 32) for using transmitting radioactive rays to generate an x-ray image including periodic intensity distribution, and an x-ray image detector (30) for detecting the x-ray image; and the grid (31) is configured by division into a plurality of modules (33). The computing/processing unit (22): divides the x-ray image into a plurality of sectional x-ray images (Imgm, n), according to the boundaries between the modules in the grid (31); for each of these sectional x-ray images, generates a sectional phase contrast image by analyzing the period pattern included in the sectional x-ray image using a Fourier transform and an inverse Fourier transform; and generates a phase contrast image of the imaging subject by bonding the obtained plurality of sectional phase contrast images.
