    • A radiographic phase-contrast imaging apparatus obtains a phase-contrast image using two gratings including the first grating and the second grating. The first and second gratings are adapted to form a moire pattern when a periodic pattern image formed by the first grating is superimposed on the second grating. Based on the moire pattern detected by the radiographic image detector, image signals of the fringe images, which correspond to pixel groups located at different positions with respect to a predetermined direction, are obtained by obtaining image signals of pixels of each pixel group, which includes pixels arranged at predetermined intervals in the predetermined direction, as the image signal of each fringe image, where the predetermined direction is a direction parallel to or intersecting a period direction of the moire pattern other than a direction orthogonal to the period direction. Then, a phase-contrast image is generated based on the obtained fringe images.
    • 射线相位成像装置使用包括第一光栅和第二光栅的两个光栅获得相位对比度图像。 当由第一光栅形成的周期性图案图像叠加在第二光栅上时,第一和第二光栅适于形成莫尔图案。 基于由放射线照相图像检测器检测到的波纹图案,通过获得每个像素组的像素的图像信号,获得与相对于预定方向位于不同位置处的像素组对应的条纹图像的图像信号, 作为每个条纹图像的图像信号,其中预定方向是与波纹图案的周期方向平行或相交的方向,而不是与周期方向正交的方向。 然后,基于获得的条纹图像生成相位对比图像。
