Zusammenfassung:The invention relates to the technical field of security inspection, in particular to a design method for a detection device of CT detection equipment. The design method comprises the following steps: 1) design of regular polygon positioning lines: designing the regular polygon positioning lines on the outer side of the circumference surface of a passage; 2) design of an x-ray source: arranging the x-ray source outside the regular polygon positioning lines in such a manner that the central axis of an emitting slit of the x-ray source passes through the center of the regular polygon; 3) design of a detector group: restraining one end point of each of a plurality of detector groups on the regular polygon positioning lines sequentially, so as to ensure that the detector groups and the x-ray source are oppositely arranged on two sides of a passage; 4) design of detector arm supports, combining and connecting a plurality of arm support units according to the geometric rule of the regular polygon, so as to form the detector arm supports; 5) design of a front collimation grid and a back collimation grid; 6) design of a detector box body takes the shape of a regular polygon. The design method has the advantages that the detection device is small in size, low in cost, and high in sealing effect and detection precision.
