    • 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.
