摘要： A first image including a projection of a portion is generated based on data representing attenuation of higher-energy radiation having a peak energy of at least 1 MeV that passes through a portion of an inspection volume. A second image including a projection of the portion is generated based on data representing attenuation of lower-energy radiation passing through the portion of the inspection volume. A dual-pixel image is created from the first image and the second image. A region of interest is selected from the dual-pixel image. A first basis function that is derived from an attenuation characteristic associated with the region of interest is selected. The region of interest is represented in terms of an amplitude associated with the first basis function and an amplitude associated with the second basis function.

摘要： A system may comprise a cathode, a target, one or more switches, and a conductive element. The cathode may be configured and arranged to generate an electron beam, and the target may be configured and arranged to emit radiation when electrons in the electron beam impact the target after being accelerated by an energy source. The one or more switches may be configured and arranged to apply either a first voltage or a second voltage from a power supply between the cathode and the target. The conductive element may be disposed between the cathode and the target so as to inhibit the electron beam generated by the cathode from reaching the target when a signal is applied to the conductive element.

摘要： A security system for detecting contraband such as explosives. The system has a source of radiation and a detector array. A detector array is made of many small detectors, each with a fast response time. The fast response time allows individual radiation photon interactions with each detector to be counted. By counting the number of interactions in an interval of time, the amount of radiation reaching the detector can be measured. The magnitude of the response from the detector to each radiation interaction allows measurement of the energy level of the photons interacting with the detector. Such a system provides significant flexibility in analyzing data collected from items under inspection. For example, objects such as contraband can be identified within the item under inspection by processing the data to accurately determine both the density and type of material.

摘要： A representation of an amount of energy incident on a radiation sensor formed from multiple sensing elements coupled together along a direction parallel to a direction of propagation of the incident radiation is received. The radiation sensor has an adjustable border positioned between any two of the multiple sensing elements. From the representation, an amount of energy incident on the radiation sensor is determined. A position of the border is selected based on the amount of energy incident on the radiation sensor. After selecting the position of the border, an absorption characteristic of a region imaged by the radiation sensor is determined.

摘要： An X-ray inspection device for detecting a specific material of interest (typically contraband, for example, weapons, drugs, money, explosives) in items of various sizes and shapes includes an X-ray source system located at an inspection region and constructed to expose the examined item to at least one beam of X-ray radiation, one or more x-ray detection systems located at the inspection region and constructed to detect x-ray radiation modified by the examined item. The X-ray inspection device also includes one or more dimension detectors constructed to measure a selected dimension of the examined item, an interface system connected to receive X-ray data and dimension data, and a computer programmed to utilize the data for recognition of the specific material of interest and to indicate its presence in the examined item. The X-ray detection systems detect transmitted and/or scattered X-ray radiation utilizing several different geometries. There may be one or more X-ray back-scatter detection systems, or one or more X-ray forward-scatter detection systems detecting X-ray radiation scattered at different angles from different surfaces of the examined item. Each detection system includes one or more arrays of X-ray detectors arranged in a linear, circular or semi-spherical geometry. Each detection system also may be connected to a displacement unit constructed and arranged to move or rotate the detector array to a selected position relative to the inspection region and the examined item.

摘要： An inspection system that forms material sensitive X-ray images of items under inspection. The images are decomposed into basis function images using basis functions representative of materials of interest. The decomposed images may be processed separately to detect concentrations of a material of interest corresponding to one or more of the basis functions. When operated in this mode, the inspection system may be used in applications such as material sorting or security screening. At least one basis function is selected to distinguish a material of interest from other materials likely contained with the item, allowing one of the basis function images to be analyzed to obtain information about a specific material of interest. The images may be automatically analyzed or may be superimposed for display with different visual characteristics assigned to the components associated with each basis function for analysis by a human operator.
