ABSTRACT:
The present invention provides an X-ray imaging apparatus and X-ray controlling method which allows appropriate X-ray control irrespective of the type and position of a subject. The X-ray controller device for controlling the X-ray emission condition of the X-ray emitter device based on the image information of a fluoroscopic image sets within one frame of the fluoroscopic image a plurality of narrow regions and one single wide region encompassing these narrow regions, selects as the formal region, from within the plurality of narrow regions and the wide region, the region in which the subject is assumed to be present, or selects as the formal region the wide region if there is no region in which the subject is assumed to be present, then control the X-ray emission condition of the X-ray emitter device based on the image information in the formal region.
