Abstract

Systems, methods, apparatus, and computer program products are provided for non-invasive scanning of an object using X-ray electromagnetic radiation. One method may include generating at least one two-dimensional X-ray radiographic image, generating composite flat-field data using the at least one two-dimensional X-ray radiographic image, a second two-dimensional X-ray radiographic image, or both, and applying flat-field image correction using the composite flat-field data to the at least one two-dimensional X-ray radiographic image.
