Abstract:
The present application is directed toward the generation of three dimensional images in a tomography system having X-ray sources offset from detectors, in particular in a system where the sources are located on a plane, while detectors are located on multiple parallel planes, parallel to the plane of sources and all the planes of detectors lie on one side of the plane of sources. A controller operates to rebin detected X-rays onto a non-flat surface, perform two dimensional reconstruction on the surface, and generate the three dimensional image from reconstructed images on the plurality of surfaces.
Abstract:
A drive-through scanning system comprises a radiation generating system arranged to generate radiation at two different energy levels and direct the radiation towards a scanning volume, detectors arranged to detect the radiation after it has passed through the scanning volume, and a controller arranged to identify a part of a vehicle within the scanning volume, to allocate the part of the vehicle to one of several categories, and to control the radiation generating system and to select one or more of the energy levels depending on the category to which the part of the vehicle is allocated.
Abstract:
The present invention is directed toward an X-ray scanner that has an electron source and an anode. The anode has a target surface with a series of material areas spaced along it in a scanning direction. The material areas are formed from different materials. The electron source is arranged to direct electrons at a series of target areas of the target surface, in a predetermined order, so as to generate X-ray beams having different energy spectra.

A mobile scanning system with a scanner including a radiation source and detectors mounted on a vehicle and arranged to scan an object, a controller mounted on the vehicle and arranged to control the scanner, an operator system arranged to be located remote from the vehicle and to communicate with the controller to enable an operator to interact remotely with the controller.
Abstract:
The present invention is a self-contained mobile inspection system and method and, more specifically, improved methods and systems for detecting materials concealed within a wide variety of receptacles and/or cargo containers. In particular, the present invention is an improved method and system with a novel boom structure that reduces the weight of the boom. The single, light-weight boom of the inspection system is relatively compact in a stowed configuration and has a low height and center of gravity lending to greater maneuverability.
Abstract:
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.
Abstract:
The present invention is an X-ray system having a source-detector module, which includes X-ray sources and detectors, for scanning an object being inspected, a scan engine coupled to the source-detector module for collecting scan data from the source detector module, an image reconstruction engine coupled to the scan engine for converting the collected scan data into one or more X-ray images, and a scan controller coupled with at least one of the source detector module, the scan engine, and the image reconstruction engine optimize operations of the X-ray system.
Abstract:
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.

The present invention is an X-ray scanning system with an X-ray source arranged to generate X-rays from X-ray source positions around a scanning region, a first set of detectors arranged to detect X-rays transmitted through the scanning region, a second set of detectors arranged to detect X-rays scattered within the scanning region, and a processor arranged to process outputs from the detectors to generate image data.
Abstract:
The present application discloses a computed tomography system having non-rotating X-ray sources that are programmed to optimize the source firing pattern. In one embodiment, the CT system is a fast cone-beam CT scanner which uses a fixed ring of multiple sources and fixed rings of detectors in an offset geometry. It should be appreciated that the source firing pattern is effectuated by a controller, which implements methods to determine a source firing pattern that are adapted to geometries where the X-ray sources and detector geometry are offset.
