摘要： A safety inspection apparatus is disclosed in embodiments of the present invention. The safety inspection apparatus includes: an x-ray source including a ray emission focal spot; and a plurality of detector modules each of which has a ray receiving surface, and which are arranged along a plurality of straight line segments. The plurality of straight line segments include a first straight line segment and two second straight line segments, and, the two second straight line segments extend from the two ends of the first straight line segment towards the x-ray source side, respectively. In a plane where the sectorial ray beam is located, a normal to the ray receiving surface of each of the detector modules at a midpoint of the ray receiving surface of the each of the detector modules passes generally through the ray emission focal spot of the x-ray source.

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.
