<P>PROBLEM TO BE SOLVED: To provide an X-ray CT device and an image processing device that can reduce artifacts in reconstructed images without degrading resolution of the reconstructed images by using a simple method. <P>SOLUTION: An X-ray CT device pertaining to one embodiment is provided with: an X-ray generating unit for exposing a subject to X-rays; an X-ray detector arranging X-ray detection elements that correspond to a plurality of channels detecting X-rays which passed through the subject, and outputting a detection signal in a prescribed direction; an image processing unit performing smoothing of projection data constituted by numeric values corresponding to the detection signals output from the X-ray detection elements corresponding to a plurality of channels, by strengthening intensity more in areas where the variation of the numeric values is large; and a reconstructing unit reconstructing images using the plurality of projection data smoothed by the image processing unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
