ABSTRACT:
An X-ray imaging apparatus includes a multi X-ray generating unit in which multiple X-ray foci are disposed in two-dimensional form at a predetermined pitch in a first direction, and a slit unit having multiple slit members each disposed opposite to its respective X-ray focus. Each slit member has multiple slits arranged in the first direction, and each of the slits forms a slice-formed X-ray beam whose lengthwise direction is a second direction that is different from the first direction. The two-dimensional detection unit detects the X-ray intensity of the formed X-ray beams at the detection surface. The X-ray imaging apparatus executes X-ray imaging at multiple positions while moving the multi X-ray generating unit and the slit unit in the first direction by the amount of the predetermined pitch, while keeping the relative positional relationship therebetween, and reconstructs an X-ray image based on the obtained X-ray intensity.
