| description | A method of correcting CT numbers in image data includes selecting at least one reference region in a CT image, wherein the selected region is a region associated with substantially same CT number when no artifacts are present in the CT image, estimating artifacts in at least one other region of the CT image based at least in part on detected CT numbers in the at least one reference region, and correcting CT numbers in the at least one other region of the CT image based on the estimated artifacts. |
