Title:
RADIOGRAPHIC SYSTEM
Document Type and Number:
Japanese Patent JP2014155508
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance accuracy of phase information for a subject in radiation phase imaging for acquiring the phase information.SOLUTION: A radiographic system 10 comprises: a grating 31 that uses a passing radioactive ray to form a radiographic image including a periodic pattern; a radiographic image detector 30 that includes multiple pixels arrayed at pixel pitches for forming moire in a relationship of a period of the periodic pattern of the radiographic image and uses these pixels to detect the radiographic image; and an operation processing part that generates a phase contrast image of a subject positioned in an irradiation field of the radioactive ray entering the grating, on the basis of modulation which occurs in the moire of an image acquired by the radiographic image detector due to the subject.
