<p>PURPOSE:To provide an X-ray CT device with which the metal artifact is reduced when a high X-ray absorbent such as metal is included in a subject. CONSTITUTION:An interest region is set from a restructured image by a means 1, and the region set as a region setting means from the interest region is interpolated by an interpolating means 2, and the projective data interpolated is restructured. One of the features of the metal artifact is a peak on the projective data, and the projective data is presumed by interpolation from the data of channel free from influence of any high absorbent such as metal, and thereby the metal artifact is reduced by restructuring this projective data corrected, and the image information concealed by the metal artifact can be displayed in such a way as well suit the surrounding situation.</p> |
