Claim Text:
1. An apparatus for ray scanning imaging, the apparatus comprising: a plurality of ray generators distributed uniformly along a circular arc, said plurality of ray generators emitting ray beams in sequence to an object to be inspected within a single scanning period, to complete scan for a single slice; and a ray detection device adapted for collecting ray projection values of the ray beams emitted by said plurality of ray generators; wherein said ray detection device comprises a plurality of linear arrays of ray detectors, each of said plurality of linear arrays of ray detectors comprises a plurality of ray detectors arranged along a straight line, wherein said plurality of linear arrays of ray detectors adjoin end to end in a same plane in sequence except that two of the plurality of linear arrays of ray detectors at both ends thereof do not adjoin each other, so as to form a semi-closed frame; and wherein the plane where said plurality of linear arrays of ray detectors are placed and a plane where said plurality of ray generators are placed being in parallel with the plane where said plurality of linear arrays of ray detectors are placed are perpendicular to a movement direction of the object to be inspected.
