Abstract: A method for operating an inspection system is disclosed in which an item under inspection may be moved between radiation sources and detectors illuminated by the sources. The radiation sources may be positioned such that radiation from at least some of the sources impinge on the radiation detectors, forming acute angles with respect to a plane having a normal direction coinciding with the first direction that are substantially in excess of three degrees. Data accumulated by the radiation detectors may be processed to form a three-dimensional tomographic data image of at least a portion of the item under inspection. The processing may be performed using an algebraic reconstruction technique using an inverse system matrix. The inverse matrix can be derived without first computing a transpose of the system matrix.

Abstract: A security system for use in connection with cargo containers and other enclosed spaces. The system monitors vibrations associated with a container and detects signals representative events indicating that an unauthorized access has been made to the container. The system may be programmed with a library of event signatures, allowing different types of events to be detected. The system may be provided with a library of signatures representing a heart beating with a beat pattern and the system may be used to detect a human or other animal within the container. Alternatively, the system may be provided with a library of signatures representing piercing the container. The system may be used to monitor containers in transit. Indications of events may be stored while the container is in transit and then communicated at a security check point.

Abstract: A method for operating an inspection system is disclosed in which an item under inspection may be moved in a first direction relative to and at least partially between at least one radiation source and at least some radiation detectors illuminated by the at least one radiation source. The radiation source and detectors may be operated such that ray paths extending linearly between the at least one radiation source and at least some of the radiation detectors form acute angles with respect to a plane having a normal direction coinciding with the first direction that are substantially in excess of three degrees. Data accumulated by the radiation detectors may be processed to form a three-dimensional tomographic data image of at least a portion of the item under inspection. In some embodiments, transmission data based upon outputs of a plurality of radiation detectors may be processed to form a tomographic image, in which, for all possible orientations of a three dimensional plane, the orientation vectors of at least some of the rays of radiation for which transmission data was accumulated and used to form the tomographic image form an angle of less than eighty-five degrees or greater than ninety five degrees with respect to the plane.

Abstract: A contraband detection system using a cone beam computed tomography scanner. The cone beam scanner allows for rapid acquisition of data for computing three dimensional density maps of objects within items under inspection. Where greater resolution is desired, the image information obtained with the cone beam computed tomography scanner may be combined with higher resolution images formed with a single view scanner. A multi-energy single view scanner may be used to additionally provide information on the effective atomic number of objects contained within items under inspection. Additionally, information obtained with the cone beam computed tomography scanner may be used to increase the accuracy of the computation of the effective atomic number of objects within the item under inspection.

Abstract: An inspection system having a user friendly operator display. Characteristics of items under inspection are represented in the display by color and brightness. Each pixel on the display is assigned an intensity representation of a first characteristic of a region of an item, such as density. Color is assigned to each pixel based on anther characteristic of the regions, such as atomic number. The intensity assigned to each pixel in the display is based in part on the color assigned to that pixel so that each pixel representing the same value of the first characteristic will appear to a human with the same brightness, regardless of the color assigned to the pixels. Such a display is used in an x-ray inspection system to represent attenuation of x-rays by brightness and effective atomic number by color.

Abstract: A reduced size CT scanner for baggage inspection has a wide angle x-ray source and multiple sets of detectors at different distances from the x-ray source. The detectors in each set are sized and positioned to maintain consistent pitch and flux levels among all detectors. Conventional reconstruction processes can be used to process the data from the CT scanner. The scanner may also be incorporated into a check-in desk in a network of scanners.

Abstract: An X-ray inspection system and methodology is disclosed. The system comprises a conveyor, an X-ray source that exposes an item under inspection to X-ray radiation and at least one X-ray detector that detects X-ray radiation modified by the item. The X-ray source and X-ray detector may be movable in any of first and second dimensions. The X-ray source may also be moved in a third dimension to zoom in and out on regions of interest in the item order inspection. The system further comprises a controller that controls movement of the X-ray source and X-ray detector, independently of each other, in any of collinear and different directions, to provide a plurality of X-ray views of the item at varying examination angles of the X-ray radiation. A processor coupled to the controller may be configured to receive and process detection information from the X-ray detector and to provide processed information to an operator interface. The operator interface may also receive instructions from an operator input and provide the instructions to the controller.
