    Abstract: The present specification discloses systems for a compact and portable X-ray transmission imaging system that is used for security inspection of small items. The system includes a housing with an X-ray tunnel for receiving an article to be inspected, a conveyor for conveying the article through the tunnel, a dual source X-ray system, with a central target, for generating two overlapping cone beams, and a two-dimensional X-ray detector system for detecting the generated dual energy X-rays.

    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.
