Abstract

An X-ray imaging apparatus is provided with a multi X-ray source and a collimator in which a plurality of slits for X-rays to pass through are two-dimensionally formed, the size and position of the slits being adjustable. A control unit, as a first control mode, controls the size and position of the slits to move an examination region in parallel, when an X-ray source is changed to a different X-ray source, such that the examination directions are parallel before and after the change. Also, the control unit, as a second control mode, controls the size and position of the slits to rotate the examination direction, when an X-ray source is changed to a different X-ray source, such that the center of the examination regions is the same before and after the change.
