Patent ID: 7945015

Claim:
An X-ray imaging apparatus comprising: 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; a slit unit having multiple slit members each disposed opposite to its respective X-ray focus, and each slit member having multiple slits arranged in the first direction, each of the slits forming an X-ray from the X-ray focus opposite thereto into a slice-formed X-ray beam whose lengthwise direction is a second direction that is different from the first direction; a two-dimensional detection unit that detects the X-ray intensity of the X-ray beams formed by the slit unit at a detection surface; a moving unit that moves the multi X-ray generating unit and the slit unit in the first direction while keeping the relative positional relationship therebetween; an executing unit that executes X-ray imaging at multiple positions while the moving unit moves the multi X-ray generating unit and the slit unit by the amount of the predetermined pitch; and a reconstructing unit that reconstructs an X-ray image based on the X-ray intensity obtained through the X-ray imaging executed by the executing unit.
