    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 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: The present specification describes methods and systems for inspecting objects by means of penetrating radiation where objects are conveyed through the penetrating radiation and subsequent images of objects are reviewed by an operator. Specifically, the present specification describes a system that decouples the synchronization between cessation of image generation on the display and image acquisition through conveyance of the article. Further, the present specification discloses methods for compensating for image acquisition inefficiencies involving article separation by the queuing conveyor and the post-stop back belt process, resulting in throughput enhancement.

    Abstract: The present specification discloses a storage system for enabling the substantially concurrent storage and access of data that has three dimensional images processed to identify a presence of a threat item. The system includes a source of data, a temporary storage memory for receiving and temporarily storing the data, a long term storage, and multiple workstations adapted to display three dimensional images. The temporary storage memory is adapted to support multiple file input/output operations executing substantially concurrently, including the receiving of data, transmitting of data to workstations, and transmitting of data to long term storage.

    Abstract: A variable mode X-ray transmission system is provided that can be operated in low or high dose rate modes depending upon the area or portion of the vehicle to be screened. In one embodiment, variable dose rate is achieved by use of a novel collimator. The systems disclosed in this application enable the scanning of a vehicle cab portion (occupied by people, such as a driver) at low dose rate, which is safe for human beings, while allowing the scanning of the cargo portion (unoccupied by people) at a high dose rate. Rapid switching from low dose rate to high dose rate operating mode is provided, while striking a balance between high material penetration for cargo portion and low intensity exposure that is safe for occupants in the cab portion of the inspected vehicle.
