Abstract
This X-ray imaging apparatus () includes a rotation mechanism () for relatively rotating an imaging system () constituted by an X-ray source (), a detector (), a first grating () and a second grating (), and an image processing unit () for generating a dark-field image based on an X-ray intensity distribution at each of a plurality of rotation angles. The image processing unit () is configured to perform a scattering correction for reducing a dark-field signal of a pixel whose dark-field signal is larger than a threshold value (V) among a plurality of pieces of pixels in the dark-field image to a set value (V).
