Multi-layer collimated industrial process gamma tomography system

摘要

PURPOSE: An industrial fixed type real-time multi-stage tomographic apparatus using gamma ray is provided to improve the resolution and accuracy of tomographic image information by employing an optical system in which n polygonal layers composed of multiple measurement modules are laminated. CONSTITUTION: An industrial fixed type real-time multi-stage tomographic apparatus using gamma ray comprises an optical system and an image generating unit. In the optical system, n layers in which a plurality of measurement modules(110) are arranged to face a subject are laminated. The image generating unit generates tomographic image information using attenuation information produced from the gamma ray outputted from each measurement module.
