摘要： A radiographic system which detects a radiation image transmitted through a subject with a radiation image detector and generates a phase contrast image of the subject, includes: a calculation section that calculates a distribution of refraction angles of radiation incident on the radiation image detector and generates the phase contrast image on the basis of the distribution of refraction angles; and a storage section that stores a correction coefficient of each pixel for making sensitivities of pixels equal. The calculation section performs sensitivity correction on a refraction angle of radiation incident on each pixel of the radiation image detector, which is calculated by imaging the subject, using the correction coefficient of the pixel stored in the storage section and generates the phase contrast image of the subject on the basis of the distribution of corrected refraction angles.

摘要： An X-ray imaging system includes an X-ray source, first and second absorption gratings, and an FPD. The first absorption grating passes X-ray emitted from the X-ray source to form a G1 image. The second absorption grating modulates intensity of the G1 image at each of relative positions to form two or more fringe images. The relative positions differ in phase with respect to a period pattern of the G1 image. The FPD detects two or more frames of image data of the fringe images. A defective pixel detector reads two or more frames of image data stored in a memory and obtains a characteristic value of an intensity modulated signal on a pixel-by-pixel basis based on the read image data. The defective pixel detector detects a defective pixel based on the characteristic value obtained.

摘要： A radiological image detection apparatus includes a first grating unit, a grating pattern unit, a radiological image detector, and an anti-scatter grating. The grating pattern unit has a period that substantially coincides with a pattern period of a radiological image formed by radiation having passed through the first grating unit. The radiological image detector detects the radiological image masked by the grating pattern unit. The anti-scatter grating is arranged on a path of the radiation incident onto the radiological image detector and removes scattered radiation. A smoothing process is performed for at least one of a surface and a backside of the anti-scatter grating intersecting with a traveling direction of the radiation.
