A method and apparatus for reducing artifacts in Computed Tomography (CT) image reconstruction. The method includes: acquiring an original reconstructed image conducting total variation processing for the original reconstructed image, to generate a total variation reconstructed image conducting initial metal artifact reduction processing for the original reconstructed image, to generate an initial metal artifact reduction reconstructed image generating a weighted image based on the total variation reconstructed image and the initial metal artifact reduction reconstructed image, wherein the weighted image reflects that the original reconstructed image contains white-band artifacts and combining a portion of the original reconstructed image and a portion of the initial metal artifact reduction reconstructed image through the weighted image to generate a final image, wherein the final image does not contain white-band artifact.
