Method and apparatus for scatter artifacts correction in industrial 3-dimensional cone beam computed tomography

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.
