    Abstract: Disclosed herein are an X-ray image apparatus and a control method for the same. The X-ray image apparatus includes an X-ray generator configured to sequentially irradiate an object with a plurality of X-rays of mutually different energy bands, an X-ray detector configured to acquire a plurality of pieces of X-ray data corresponding to the plurality of mutually different energy bands by detecting X-rays transmitted through the object, an image processor configured to convert the acquired plurality of pieces of X-ray data into a plurality of X-ray images and separate blood vessel X-ray images of the object from the plurality of X-ray images, and a controller configured to control operations of the X-ray generator so that the sequentially irradiated plurality of X-rays of the mutually different energy bands are repeatedly irradiated for fixed cycles. The X-ray generator may be configured to sequentially irradiate the object with the plurality of X-rays for a first time interval in the fixed cycles, and the first time interval may be different from a second time interval that is a time interval between a time point at which a final X-ray of a single cycle among the fixed cycles is irradiated and a time point at which a first X-ray of the following cycle among the fixed cycles is irradiated.
