    摘要: The present disclosure relates to a security scanning inspection system and method. The security scanning inspection system comprises a detector, a scanning device and a controller, wherein the detector is configured to detect a protective attribute of an object to be inspected; the scanning device is movably arranged and the scanning device is configured to emit a scanning ray during movement to perform a security scanning inspection on the object to be inspected, the scanning device comprising at least two working modes, wherein a dose of a scanning ray in each working mode is different from a dose of a scanning ray in any other working modes; and the controller configured to select a working mode of the scanning device according to the protective attribute of the object to be inspected detected by the detector.

    摘要: The present disclosure discloses a radiation inspection system and a radiation inspection method. The radiation inspection system comprises a radiation source and a beam modulating device. The beam modulating device comprises a first collimating structure disposed at a beam exit side of the radiation source and a second collimating structure disposed at a beam exit side of the first collimating structure. The second collimating structure is movable relative to the first collimating structure to change a relative position of the first collimating port of the first collimating structure with the second collimating port of the second collimating structure, and the beam modulating device is shifted between a first operational state in which the beam modulating device modulates an initial beam into a fan beam, and a second operational state in which the beam modulating device modulates the initial beam into a pencil beam variable in position.

    摘要: The present disclosure provides a scanned image correction apparatus, method and a mobile scanning device. The apparatus includes an image collector, an arm swing detector, and an image processor. The image collector is configured to collect a scanned image of an object under inspection during a scanning process of scanning the object under inspection by the mobile scanning device, and determine an image parameter of the scanned image. The arm swing detector is disposed at a monitor point on a detector arm of the mobile scanning device, and configured to detect a displacement offset of the detector arm in a specified direction and build an arm swing model of the detector arm. The image processor is configured to determine a change relationship between the image parameter of the scanned image and the displacement offset of the detector arm, and correct the scanned image based on the change relationship.
