Method and apparatus for metal artifact reduction in industrial 3-dimensional cone beam computed tomography

Abstract

Provided is a method and apparatus for metal artifact reduction in industrial three-dimensional (3D) cone beam computed tomography (CBCT) that may align computer-aided design (CAD) data to correspond to CT data, generate registration data from the aligned CAD data, set a sinogram surgery region corresponding to a metal region based on the registration data, perform an average fill-in process on the CT data based on the registration data, update data of the sinogram surgery region based on the averaged filled-in information, and reconstruct a 3D CT image from the updated sinogram data with surgery region.
