FIELD: physics.
SUBSTANCE: invention discloses an X-ray imaging device and an X-ray imaging method for use in the X-ray imaging device. The X-ray imaging device includes a separating element configured to spatially separate X-rays generated by an X-ray generating unit, and an array of scintillators, which includes a plurality of first scintillators lying thereon, the separated X-rays falling on the first scintillators. Each of the first scintillators is made such that intensity of fluorescence caused by X-rays varies according to the point of incidence of the X-rays. The X-ray imaging device further includes a detector which detects intensity of fluorescence emitted by the array of scintillators.
EFFECT: high accuracy of phase shift information.
