| 内容記述 | One of the most noteworthy aspects of computed tomography (CT) based on nuclear resonance fluorescence (NRF) transmission is the isotope selectivity that makes it possible to discern an isotope of interest from other isotopes within a sample, which is a significant technique in nuclear engi-neering. We experimentally obtained a three-dimensional (3D) isotope-selective CT image based on a NRF transmission method (3D NRF-CT) for the enriched lead isotope distribution of 208Pb in a previous study. Since the NRF-CT imaging technique requires a considerable data accumulation time, it took 48 h to obtain an image with a resolution of 4 mm/pixel in the horizontal plane and 8 mm/pixel in the vertical plane for a cylindrical sample with a diameter of 25 mm and a height of 20 mm using a laser Compton scattering (LCS) gamma-ray beam with a beam size of 2 mm and a flux density of 10 photons/s/eV. Improving the NRF-CT image resolution with the existing hardware is challenging. Therefore, we proposed an alternative method to improve the NRF-CT image quality using the fusion visualization (FV) technique by combining the NRF-CT image including isotopic information with a gamma-CT image, which provides better pixel resolution. The 3D gamma-CT image for the same sample was measured at the same beamline BL1U in the UVSOR-III synchrotron radiation facility under similar experimental conditions except for the LCS gamma-ray beam flux and beam size. Obtaining a 3D gamma-CT image with a resolution of 1 mm/pixel took 5 h using an LCS gamma-ray beam with a beam size of 1 mm and a flux density of 0.7 photons/s/eV. The data processing of the FV technique has been developed, and the 3D NRF-CT image quality was im-proved. | |||||
