Abstract: The present specification discloses an X-ray scanning system having a shield surrounding an X-ray source of an X-ray inspection system, the shield comprising a first material or a combination of the first material and a second material; and a thickness that keeps a radiation dose below a predefined limit at a plurality of locations on a boundary of a defined exclusion zone, wherein the plurality of locations change as the X-ray source moves in a scan direction, and wherein the thickness of the shield varies non-uniformly as a function of a plurality of angles of radiation.

Abstract: The present specification discloses methods for inspecting liquids, aerosols and gels (LAGs) for threats. The method includes scanning LAGs packed in plastic bags in a multiple step process. In a primary scan, the bag is scanned using dual energy CT technique with fan beam radiation. In case of an alarm, the alarming LAG container is scanned again using coherent X-ray scatter technique with cone beam radiation. The system has a mechanism to switch between two collimators to produce either fan beam or cone beam. The system also has a mechanism to position the target properly for scanning and prevent container overlap when scanning multiple LAG containers in a bag.
