  • METHOD AND APPARATUS FOR METAL ARTIFACT REDUCTION IN COMPUTED TOMOGRAPHY
    Publication number: 20090074278
    Abstract: A method for reducing artifacts in an original computed tomography (CT) image of a subject, the original (CT) image being produced from original sinogram data. The method comprises detecting an artifact creating object in the original CT image; re-projecting the artifact creating object in the original sinogram data to produce modified sinogram data in which missing projection data is absent; interpolating replacement data for the missing projection data; replacing the missing projection data in the original sinogram data with the interpolated replacement data to produce final sinogram data; and reconstructing a final CT image using the final sinogram data to thereby obtain an artifact-reduced CT image.
