An X-ray imaging apparatus and control method for the X-ray imaging apparatus are provided. The X-ray imaging apparatus includes an X-ray source to generate X-ray beams, and to irradiate the X-ray beams onto an object; a first X-ray detector configured to detect X-ray beams transmitted through the object and generate a first phase contrast signal; an X-ray obtainer including an X-ray collimator and a second X-ray detector, wherein the X-ray collimator is spaced apart from the object by a predetermined distance, and configured to focus the X-ray beams transmitted through the object, and wherein the second X-ray detector is configured to detect the focused X-ray beams and generate a second phase contrast signal based on the detected X-ray beams; and an image processor configured to create a phase contrast image and an absorption image of the object.
