Abstract
A double-radiant-source framework used for a radiation detecting system for containers, having a horizontal accelerator, a vertical accelerator and a gantry tower composed of a left vertical girder, a right vertical girder, an upper cross girder, and a lower cross girder. A horizontal collimator and accelerator, and a vertical collimator and accelerator, are fixed on the left vertical girder and the upper cross girder of the gantry tower, respectively, and emit radiation beams as two planes oriented parallel to each other. Detector modules are disposed inside the double-detector arm of the right vertical girder, and inside the upper cross girder and the lower cross girder, respectively, to receive the two emitted planes of radiation beams. The container detecting system can reduce the area covered by the scanning channel of the system, and make the transportation, installation and use convenient, and improve the quality of the detected images.
