| 内容記述 | Computed Tomography (CT) using X-ray attenuation by atomic effects has been used in various fields such as medical diagnosis. CT scanning of high density and high-Z industrial object using gamma-rays from radioisotopes, Bremsstrahlung gamma-rays in the MeV energy region, and quasi-monochromatic gamma-rays generated by laser Compton scattering (LCS) have been studied. However, even if such technologies are used, it is difficult to distinguish clearly a high-Z element from other high-Z elements by the atomic attenuation. Previous studies [4,5] have proposed a novel method to measure CT images for high density and high-Z objects using identification of a specific nuclide with Nuclear Resonance Fluorescence (NRF-CT). Here we show the demonstration of the isotope imaging with NRF-CT and a LCS gamma-ray beam. We measured a two-dimensional CT image of a lead isotope, 208Pb, inside a sample of an aluminum cylinder including an iron rod, a lead rod, and a hole (air). The preliminary NRF image includes both effects of atomic attenuation and nuclear resonant attenuation. By subtracting the atomic attenuation measured by a conventional method at the same time, a clear 208Pb isotope CT image was measured. | |||||
