Abstract: A security scanning system comprises a first stage module having at least one X-ray source and at least three first detectors that are line-shaped and arranged in mutually different orientations and have at least dual energy resolution. A group of carry-on items on a carrier are scanned simultaneously in the first stage module solely by transmission contrast radiography generating projections of two-dimensional image data. A processing device reconstructs a 3D representation of the carry-on items and analyzes the 3D representation to determine whether further scanning is required.
