  • Method of and system for reducing metal artifacts in images generated by x-ray scanning devices
    Patent number: 6721387
    Abstract: A method of reducing metal artifacts in a computed tomography (CT) system includes: A. generating a preliminary image from input projection data collected by the CT system; B. identifying metal objects in the preliminary image; C. generating secondary projections from the input projection data by removing projections of objects having characteristics that may cause the objects to be altered in a final artifact-corrected image. D. extracting the projections of metal objects identified in step B from the secondary projection data generated in step C. E. generating corrected projections by removing the projections of the metal objects extracted in Step D from the input projection data. F. generating a final image by reconstructing the corrected projections generated in step E and inserting the metal objects identified in Step B into the final image.
