Abstract
A radiation phase image radiographing apparatus, including a radiation emission unit having multiple radiation sources for emitting radiation onto a subject, the radiation sources being distributed such that radiation emitted from each of the radiation sources and transmitted through the subject forms a part of a projected image of the subject, a first diffraction grating configured to be exposed to the radiation emitted from the multiple radiation sources of the radiation emission unit and to produce a Talbot effect by the exposure, a second diffraction grating for diffracting the radiation diffracted by the first diffraction grating, and a radiation image detector for detecting the radiation diffracted by the second diffraction grating.
