The present invention discloses apparatus and method for ray scanning imaging. The apparatus comprises a plurality of ray generators and a ray detection device. The plurality of ray generators are arranged uniformly along a circular arc and emit ray beams in sequence or simultaneously to an object to be inspected within a single scanning period. The ray detection device may be either in a multi-segmental semi-closed configuration composed of a plurality of linear arrays of ray detectors or in a circular arc configuration where a plurality of ray detection units arranged uniformly along a circular arc. During the inspection, the apparatus is advantageous in obtaining the complete ray projection values without rotation thereof, so as to effectively shorten the inspection time. |
