The present invention provides for an improved scanning process with a stationary X-ray source arranged to generate X-rays from a plurality of X-ray source positions around a scanning region, a first set of detectors arranged to detect X-rays transmitted through the scanning region, and at least one processor arranged to process outputs from the first set of detectors to generate tomographic image data. The X-ray screening system is used in combination with other screening technologies, such as NQR-based screening, X-ray diffraction based screening, X-ray back-scatter based screening, or Trace Detection based screening.

X-ray tomographic inspection system for the identification of specific target items

An X-ray scanner comprises an array (12) of X-ray detectors (16) arranged in cylindrical configuration around an imaging volume (28), and a multi-focus X-ray source (20) which extends in a helical configuration around the outside of the detector array (12). A helical gap (24) in the detector array (12) allows X-rays from the source (20) to pass through the patient (26) in the imaging volume (28), and onto the detectors (16) on the opposite side of the scanner. The source (20) is controlled so that the X-rays are produced from a number of source points along the helical locus (23) to produce a tomographic image. As the patient is stationary and the source point varied electrically, the scanning rate is sufficient to produce a series of images which can be displayed as a real time three-dimensional video image.

X-ray scanning system

The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.

X-ray inspection system that integrates manifest data with imaging/detection processing

The present application discloses an X-ray scanner having an X-ray source arranged to emit X-rays from source points through an imaging volume. The scanner may further include an array of X-ray detectors which may be arranged around the imaging volume and may be arranged to output detector signals in response to the detection of X-rays. The scanner may further include a conveyor arranged to convey an object through the imaging volume in a scan direction, and may also include at least one processor arranged to process the detector signals to produce an image data set defining an image of the object. The image may have a resolution in the scan direction that is at least 90% as high as in one direction, and in some cases two directions, orthogonal to the scan direction.

Disclosed herein is a processing station (10) for registering a passenger's luggage for a trip. The processing station (10) comprises an injector (14) for receiving a piece of luggage associated with the passenger. A plurality of sensors (16a-16i) are associated with the injector. A weighing machine (18) is also associated with the injector (14) for weighing the piece of luggage whilst in the injector (14). The luggage processing (station 10) also comprises a user interface (20) for receiving various inputs for confirming that a passenger has checked-in and to display information to the passenger during processing of the piece of luggage. A controller (28) is associated with the sensors (16a-16i) and weighing machine (18) and the user interface (20). The controller (28) is adapted to accept the piece of luggage if the input received via the passenger's boarding pass or identification card indicate that the passenger has checked-in for the trip, feedback from the sensors (16a-16i) indicates that predetermined criteria are met, and if feedback from the weighing machine (18) indicates that weight of the piece of luggage is within a predetermined limit.
