<p>One aspect of the disclosed invention relates to an X-ray imaging apparatus which makes an inner image of an object by emitting an X-ray to the object and, more particularly, to an X-ray imaging apparatus capable of reducing an amount of X-rays emitted to the object and implementing various interest regions. The X-ray imaging apparatus according to one aspect of the disclosed invention includes: an X-ray source which emits the X-ray to the object, a filtering unit which is located on the front side of the X-ray source and forms the interest region through which the X-ray passes, and an X-ray detector which obtains a plurality of X-ray images by detecting the X-ray emitted to the object. The filtering unit includes a base plate which forms the emission region by passing the emitted X-ray, and at least one moving plate which forms the interest region by closing at least part of an emission region and moves with regard to the interest region to symmetrically or asymmetrically form the interest region.</p> |
