摘要： The present invention discloses a detecting method of an article detection apparatus composed of an individual DR subsystem and an individual CT subsystem, the method comprising: obtaining a first projection data on ray attenuation coefficient by using the DR subsystem to project an A-layer of an article at a first projection angle, and obtaining a second projection data on ray attenuation coefficient by using the CT subsystem to project an A-layer of the article at a second projection angle different from the first projection angle; and judging whether an A-layer of the detected article contains a dangerous article based on the first projection data and the second projection data so as to obtain a first judgment on an A-layer of the detected article. In the present invention, by combining the projection data of the DR subsystem and the projection data of the CT subsystem, the amount of data information used to judge the detected article is greatly increased, therefore, both the detection accuracy and speed are improved.

摘要： System and method for XRD-based threat detection. An object is scanned with a first threat detection system. One or more alarm objects are identified. Data about the one or more alarm objects is passed from the first threat detection system to a second threat detection system and is used to move and/or to rotate the object in a predetermined ray path that decreases attenuation of scattered x-ray radiation. Also disclosed is a secondary collimator for XRD-based false alarm resolution in computed tomography {“CT”) threat detection systems. The secondary collimator comprises one or more slit apertures configured to provide a multi-angle capability that extends a range of momenta for which XRD intensities are measured for a predetermined range of photon intensities.

摘要： A system and methods for identifying contents of an enclosure such as an air cargo container. A three-dimensional image indicative of at least one of the CT number and the density of contents of the enclosure is obtained using penetrating radiation such as x-rays. If one or more suspect regions are identified among contents of the enclosure, a collimated neutron beam is activated to traverse each suspect region and fluorescent emission from the suspect region is detected, allowing material within the suspect region to be characterized based at least on the detected fluorescent emission. Additionally, the collimated neutron beam may be employed for neutron imaging of the contents of the enclosure.

摘要： However, this requires additional collimating means and this reduces the photon flux applied to the detectors. Due to this, longer measuring times may be required. Furthermore, the geometry is incompatible to known cone-beam CT-scanners. According to an exemplary embodiment of the present invention, a cone-beam CSCT scanner is provided using energy resolving detectors with a collimator arranged on the detectors, which allows spatially-resolved reconstruction of the scattering function. Advantageously, this may allow for an improved scanning speed in baggage inspection or medical applications.
