摘要：
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.
