    Abstract: 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.

    Abstract: The present invention discloses a CT security inspection system for baggage. The CT security inspection system comprises a scanning passage through which a baggage enters and exits the CT security inspection system for baggage, a X-ray source provided at one side of the scanning passage, and, a gantry provided at an opposite side of the scanning passage, and on which a plurality of detector units are mounted. In each of the detector units, a vertex point of at least one detector unit is positioned in a circular arc with its center at a center of the scanning passage, and the detector units are arranged successively. All the detector crystal receiving faces of the plurality of detector units are within a scope of radiating ray beams with its center at a target of the X-ray source. In each of the detector units, a connection line between a midpoint of at least one of the detector crystal receiving faces and the target of the X-ray source is normal to the corresponding detector crystal receiving face.

    Abstract: A CT system and method thereof are disclosed. The system includes: a conveyor mechanism; a first scanning stage configured to scan the object and generate a first digital signal; a second scanning stage spaced from the first scanning stage at a preset distance in a direction of the object's movement; a processing device configured to reconstruct a CT image of the object at a first image quality based on the first digital signal, and analyze the CT image; and a control device configured to adjust a scanning parameter of the second scanning stage based on an analysis result of the processing device to cause the second scanning stage to output a second digital signal. The processing device reconstructs a CT image of the object at a second image quality higher than the first image quality at least based on the second digital signal. The system takes full advantage of the distributed ray sources which replace the normal slip ring technology.
