X-RAY IMAGING APPARATUS AND CONTROL METHOD FOR THE SAME

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.

主权项

1. An X-ray imaging apparatus for forming a phase contrast image, the apparatus comprising:
an X-ray source which is configured to generate X-rays and to emit the generated X-rays toward a subject; an X-ray detector which is spaced apart from the subject by at least a predetermined distance and which is configured to detect X-rays which have propagated through the subject and to separate the detected X-rays into a respective plurality of energy bands in order to acquire respective 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.
