摘要：
Disclosed are an X-ray imaging apparatus, which may acquire different phase contrast image signals on a per energy band basis simultaneously without moving a detector or emitting X-rays multiple times by using a photon counting detector that separates detected X-rays into a plurality of energy bands, and a control method for the same. The X-ray imaging apparatus includes an X-ray source which is configured to generate X-rays and emit the X-rays toward a subject, an X-ray detector which is spaced apart from the subject by a predetermined distance and configured to detect X-rays which have propagated through the subject, and to separate the detected X-rays into a plurality of energy bands in order to acquire phase contrast image signals on a per energy band basis, and an image processor which is configured to form a phase contrast image of the subject by using the acquired phase contrast image signals.
