Abstract
This X-ray phase contrast imaging apparatus (100) includes an X-ray source (1) that radiates continuous X-rays, a first grating (3) that forms a self-image, a second grating (4), a detector (5) that detects the continuous X-rays, and a third grating (2) arranged between the detector (5) and the first grating 3. The first grating (3), the second grating (4), and the third grating (2) are arranged so as to satisfy conditions of predetermined formulas.
