Abstract: |
The pinhole back-scatter imaging equipment comprises X-ray source, fan collimator and detector, and its structure is characterized by that the ray emitted from X-ray source is passed through fan collimator to form fan beam, the fan beam ray is emitted on the body to be tested, and scattered, and passed through the designed pinhole collimator and recivered by array detector. As compared with existent technology it can fully utilize X-ray source, and can greatly raise imaging speed, resolution and mechanical stability, and is applicable to all x-ray imaging devices of x-ray examination system, specially is applicable to various container inspection system for customs. |
