Coherent Scatter Computed Tomography for Core Composition Analysis of Intact Kidney Stones - Prospective Clinical Study
… rate of single or multiple minerals. As current methods have been shown reliable from a clinical perspective, they may also be, due to sampling bias, prone to missing the core components from the analysis. This work shows that coherent scatter computed tomography (CSCT) is a composition-imaging, …
