Abstract: A method and apparatus correct a computed tomography (CT) image with motion artifacts. The method of correcting a CT image may include: obtaining a reconstruction image of an object by reconstructing an X-ray projection image; measuring a parameter value related to motion artifacts that occur due to movement of the object in at least one of the X-ray projection image or the reconstruction image; calculating a correction possibility for the reconstruction image based on the measured parameter value; and determining whether to perform correction on the reconstruction image based on the calculated correction possibility.

Abstract: A medical imaging apparatus includes an X-ray source configured to irradiate X-rays to an object; an X-ray detector configured to detect the X-rays radiated from the X-ray source to obtain projection data; and an image processor configured to reconstruct the projection data based on a motion parameter representing movement of at least one of the object, the X-ray source, and the X-ray detector, and to generate a medical image by applying a weighting process to the reconstructed projection data.
