To develop an isotope selective computed tomography imaging technique, a flat-laser Compton scattering γ-ray beam (F-LCS) by using a helical undulator installed in a storage ring has been proposed. An LCS beam with a broad energy spectrum and spatia

One of the most noteworthy aspects of computed tomography (CT) based on the nuclear resonance fluorescence (NRF) transmission method is the isotope selectivity that makes it possible to discern an isotope of interest from other isotopes within a samp
