<p>The present invention relates to an apparatus and a method for obtaining a CT image. Particularly, the present invention relates to an apparatus and a method for obtaining a CT image capable of reducing production costs and objectively correcting a beam hardening phenomenon by using a correction phantom. The present invention is to provide an apparatus for obtaining a CT image. The apparatus for obtaining a CT image includes an object CT-photographed; a correction phantom photographed and arranged near the object; a photographing part detecting a X-ray penetrating the phantom and the object; and a correction part receiving CT data from the photographing part, obtaining beam hardening information by using the phantom data obtained from the correction phantom among the received data, and correcting the beam hardening artifact of the object data obtained from the object.</p> |
