  • Method and apparatus for scatter artifacts correction in industrial 3-dimensional cone beam computed tomography
    Patent number: 11547379
    Abstract: Provided are a method and apparatus for correcting scattering artifacts in industrial three-dimensional (3D) cone beam computed tomography (CT) that may prepare raw data acquired from a subject through computed tomography (CT) and a primary signal acquired from shape prior information of the subject, may estimate a scatter kernel based on the raw data and the primary signal, may acquire result data by removing, from the raw data, a scatter signal estimated based on the scatter kernel, and may generate an image from the result data.
    Type: Grant

  • Method and apparatus for metal artifact reduction in industrial 3-dimensional cone beam computed tomography
    Patent number: 11080900
    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.
