Abstract: The present specification discloses a high speed scanning system for scanning cargo carried by rail. The system uses of a two-dimensional X-ray sensor array with, in one embodiment, a cone-beam X-ray geometry. The pulse rate of X-ray source is modulated based on the speed of the moving cargo to allow a distance travelled by the cargo between X-ray pulses to be equal to the width of the detector, for a single energy source, and to half the width of the detector for a dual energy source. This ensures precise timing between the X-ray exposure and the speed of the passing object, and thus accurate scanning of cargo even at high speeds.

Abstract: The present specification describes a compact, hand-held probe or device that uses the principle of X-ray backscatter to provide immediate feedback to an operator about the presence of scattering and absorbing materials, items or objects behind concealing barriers irradiated by ionizing radiation, such as X-rays. Feedback is provided in the form of a changing audible tone whereby the pitch or frequency of the tone varies depending on the type of scattering material, item or object. Additionally or alternatively, the operator obtains a visual scan image on a screen by scanning the beam around a suspect area or anomaly.

Abstract: An X-ray imaging inspection system for inspecting items comprises an X-ray source 10 extending around an imaging volume 16, and defining a plurality of source points 14 from which X-rays can be directed through the imaging volume. An X-ray detector array 12 also extends around the imaging volume 16 and is arranged to detect X-rays from the source points which have passed through the imaging volume, and to produce output signals dependent on the detected X-rays. A conveyor 20 is arranged to convey the items through the imaging volume 16.

Abstract: The present specification discloses systems and methods for identifying and reporting contents of a tanker, container or vehicle. Programmatic tools are provided to assist an operator in analyzing contents of a tanker, container or vehicle. Manifest data is automatically imported into the system for each shipment, thereby helping security personnel to quickly determine container contents. In case of a mismatch between container contents shown by manifest data and the contents as ascertained from the scanning system, the container or vehicle may be withheld for further inspection.

Abstract: A dual energy based X-ray scanning system has a linear detector array with high and low energy detectors. A signal processing method is employed that accounts for varying angles at which the transmitted X-rays impinge upon the detectors and also the varying order in which the transmitted X-rays pass through the high and low energy detectors. This yields both high resolution in the generated images and better penetration performance.
