Scanning systems may include a stator, a rotor supporting at least one radiation source and at least one radiation detector rotatable with the rotor, and a motivator operatively connected to the rotor. The stator, the rotor, the at least one radiation source, and the at least one radiation detector may be located within a housing. A conveyor system may extend through the housing and the rotor. A shielding system including a series of independently movable energy shields sized, shaped, and positioned to at least partially occlude a pathway along which the conveyor system extends may extend from an entrance to the housing, through the rotor, to an exit from the housing. A control system may be configured to cause the shielding system to automatically and dynamically move individual energy shields in response to advancement of one or more objects supported on the conveyor system.

Provided are CT scanning systems and architectures that utilize a unique approach to scanning large objects. Various embodiments of the architecture incorporate a horizontally mounted CT gantry. The horizontal gantry can be raised or stored in a raised position so that a pallet or other object can be moved into a scanning position under the gantry. The gantry is then lowered to enable a quickly executed a scan. Addition objects can be quickly positioned (once the gantry is raised) for subsequent scans allowing for greater throughput than conventional approaches.

Imaging systems and methods are provided for detecting objects that may be hidden under clothing, ingested, inserted, or otherwise concealed on or in a person's body. An imaging assembly, e.g., X-ray source and X-ray detector, and mechanisms, e.g., a translational mechanism for vertically moving the imaging assembly, may be configured to reduce the overall form factor of such imaging systems, while still retaining an ability to perform full/complete imaging of a subject.

The present specification discloses a multi-view X-ray inspection system having, in one of several embodiments, a three-view configuration with three X-ray sources. Each X-ray source rotates and is configured to emit a rotating X-ray pencil beam and at least two detector arrays, where each detector array has multiple non-pixellated detectors such that at least a portion of the non-pixellated detectors are oriented toward both the two X-ray sources.

An imaging apparatus 10 for generating an image of a subject including a scanning arrangement which includes an energy emitting source 20 and a detector 22 housed within a housing 12. The housing defines a scanning zone 24 in which the subject is operatively positioned for scanning A displacing arrangement 36 which includes a U-shaped belt-and-pulley drive arrangement is configured to displace the scanning arrangement relative to the housing 12 in a scanning direction. The housing 12 has a first door and second door defining a substantially linear pathway through the scanning zone. A motor 38 and horizontal drive belts 40 are disposed below the scanning zone and are not displaced relative to the housing in the scanning direction in which the energy emitting source and detector are displaced during scanning such that the displacing arrangement does not restrict or impede movement of the subject through the scanning zone.

The invention provides methods, systems and detector arrangements for scanning an object moving in a first direction that includes the steps of irradiating the object with radiation having a peak energy of at least 900 keV, providing a first detector region having a thickness of at least 2 mm and a second detector region having a thickness of at least 5 mm where the second detector region is arranged to receive radiation that has passed through the first detector region, and detecting the radiation after it has interacted with or passed through the object in order to provide information relating to the object.

The present disclosure relates to an imaging device for use in vehicle security check and a method therefor, and belongs to the field of security check. The imaging device for use in vehicle security check includes: a radiation source device including a first ray unit configured to emit a first ray beam by a first predetermined spread angle to allow the first ray beam to penetrate a first part of a vehicle to be inspected passing through an inspection lane at a preset speed; and a detector device including a first detector unit arranged corresponding to the first ray unit, and configured to receive the first ray beam. The radiation source device is at least partially arranged on the road surface of the inspection lane, and the first detector unit is arranged at a first side of the inspection lane.
