Summary:Urinary stones have four main types of components: calcium, uric acid, ammonium magnesium phosphate, and cystine, and the type of treatment must be selected according to these types. Although X-ray computed tomography (CT) is currently the most promising method for differentiating the component types of urinary stones in vivo, both conventional and dual-energy CTs are subject to limits in this component differentiation. In this paper, we show the usefulness of an energy-resolved CT system for determining urinary stone components. Standard laboratory chemicals were used as substitutes for true urinary stones, and the effective atomic numbers of the chemicals were estimated to see if they could be used to identify the different types of urinary stones.
