CT imaging based on NRF transmission method has an advantage of isotope selectivity. Using an LCS gamma-ray beam in UVSOR, we demonstrated a 3D NRF-CT image with 4 mm pixel resolution for a sample containing ²⁰⁸Pb isotope. To improve the NRF-CT image quality, a fused visualization technique in combination with a gamma-CT image is introduced
