Claim:
1. An X-ray imaging apparatus comprising: an X-ray source configured to generate X-ray beams and configured to emit the X-ray beams in an emission direction onto an object; a first X-ray detector located adjacent to the object and configured to detect X-ray beams transmitted through the object and configured to generate a first phase contrast signal based on the detected X-ray beams; 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 to 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 based on the first phase contrast signal generated by the first X-ray detector and the second phase contrast signal generated by the second X-ray detector, wherein the X-ray source and the X-ray collimator are configured to move in a direction parallel to the emission direction.
