X-ray inspection system with two flat panel detectors for extra-large object inspection

摘要

The medical imaging technologies and the industrial ones have benefitted from each other. For a baggage inspection for example, multiple-detector helical CT scanning technology has been deployed that was originally developed for a fast volumetric imaging of a patient in clinics. In a helical CT, the detector array and the x-ray source are rotating continuously in a gantry with the slip-ring technology, and the object is moving along the rotation axis. With the slip-ring technology, an elaborate x-ray cable and drum system can be eliminated but may increase the production cost and instability of the system.
