Abstract
This paper introduces a novel high-energy and high-resolution X-ray computed tomography system called eXTRACT. Preliminary experimental testing was performed of the penetration capability and structural resolution achieved by the system, and the results are reported. The X-ray source realized both bremsstrahlung X-rays with an average energy of 1â¯MeV and the focal size of 100â¯Î¼mâ¯at the same time. Using 970 physical channels of high-energy X-ray line detectors and a modified offset scanning method, the CT reconstruction of 4286 by 4286 pixels were achieved for a single sinogram from a single fan beam scanning. The performance was further investigated by scanning several material standards. The penetration capability of 400â¯mm or more, represented by a longitudinal dimension of the object, was recorded in case of scanning aluminum. The structural resolution of 0.1â¯mm by 0.1â¯mm line and space structure under the field of view size of 300â¯mm in the diameter is also verified.
