摘要： The present disclosure discloses an inspection device, an inspection method and an inspection system. The device comprises a distributed ray source comprising multiple source points; a light source collimator configured to converge the rays generated by the distributed ray source to form an inverted fan-shaped ray beam; a scatter collimator configured to only allow rays scattered at one or more particular scattering angles which are generated by the rays from the light source collimator interacting with inspected objects to pass; at least one detector each comprising multiple detection units which have an energy resolution capability and are substantially arranged in a cylindrical surface to receive the scattered rays passing through the scatter collimator; and a processing apparatus configured to calculate energy spectrum information of the scattered rays from the inspected objects based on a signal output by the detectors.

摘要： CT scanning of transportation containers is performed by generating X-rays at various points at the opposite sides of the containers, detecting the X-rays passing through the containers, and analyzing the data received to determine the presence of contraband. The X-rays are generated by modulating a magnetic field through which a high-energy electron beam passes to deflect the beam successively to different targets positioned around the sides of the container, while the electron beam source remains stationary. The X-rays are detected by an array of cells using X-ray responsive storage phosphor material to emit light which is sent to analyzing and comparing equipment. The targets and detectors and the cargo container are moved relative to one another to scan a selected volume of the container.

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 variable-ratio neutron-gamma ray source comprises a neutron generator, a shield, a collimator, and an external gamma target. The neutron generator generates neutrons and the shield reduces external radiation exposure. The collimator collimates the neutrons into a neutron beam that traverses the shield. The external gamma target generates a dual neutron-gamma ray beam from the neutron beam, wherein the dual neutron-gamma ray beam has a variable neutron-gamma ratio as a function of a thickness of the external gamma target.
