Abstract

A computed tomography (CT) system using high-energy monochromatic photons is one of the best choices for non-destructive tests, to detect flaws or defects in manufactured items for the purpose of improving quality control, and quality assurance. We have developed such a CT system based on laser-Compton X-rays, which were generated with an electron accelerator and a laser beam. Using 10 MeV laser-Compton X-rays, an experimental study for non-destructive tests of concrete specimens with computed tomography were performed. We successfully obtained CT images.
