Estimation of the sugar content of fruit by energy-resolved computed tomography using a material decomposition methodWe have been developing energy-resolved X-ray computed tomography (ER-CT) using a novel detector system called a transXend detector, which measures Xrays as electric current and gives the energy distribution of X-rays by unfolding analysis. This paper presents the results of the sugar content measurements of kiwifruit samples by ER-CT. Because the change of linear attenuation coefficients as a function of sugar content was small, we used a material decomposition method instead of the unfolding method to deduce the linear attenuation coefficient from the measured electric current. The obtained sugar contents showed good agreement with those measured by a refractometer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
