Abstract

The invention discloses an apparatus and a method for ray scanning imaging. The apparatus may comprise a plurality of ray generators and a ray detection device, wherein the plurality of ray generators are uniformly distributed along an arc and located in one scanning period and successively or simultaneously emit bundles of rays to a to-be-detected object, the ray detection device may be of a multi-section semi-closed structure composed of a plurality of ray detector linear arrays or of a circular-arc structure, and the ray detection device is provided with a plurality of ray detection units uniformly distributed along an arc. In the whole process of detection, the apparatus can rapidly obtain complete ray projection values without rotation, so time for detection is effectively reduced.

Description

technical field [0001] The invention relates to the field of radiation imaging, in particular to equipment and methods for ray scanning imaging. Background technique [0002] At present, due to the increasing attention of security inspections around the world, radiation imaging equipment has been widely used in public places and key departments such as airports, stations, customs, subways, docks, etc., so as to perform efficient and stable security inspections on luggage, goods and other items. [0003] Radiation imaging equipment is based on the principle of exponential attenuation of rays. The radiation beam emitted by the radiation source scans the inspection object. The radiation beam passes through the inspection object and is received by the radiation acquisition device. According to the ray detection value received by the ray acquisition device, a three-dimensional image can be synthesized or reconstructed and displayed.
