Abstract

•A precise clinical definition of renal cortex.•A localization algorithm for the outer and the inner layers of the renal cortex.•A purely delineation-based algorithm, which is not only accurate but also extremely efficient.•A non-uniform graph search method is presented to obtain accurate segmentation. [Display omitted] This paper introduces a model-based approach for a fully automatic delineation of kidney and cortex tissue from contrast-enhanced abdominal CT scans. The proposed framework, named CorteXpert, consists of two new strategies for kidney tissue delineation: cortex model adaptation and non-uniform graph search. CorteXpert was validated on a clinical data set of 58 CT scans using the cross-validation evaluation strategy. The experimental results indicated the state-of-the-art segmentation accuracies (as dice coefficient): 97.86% ± 2.41% and 97.48% ± 3.18% for kidney and renal cortex delineations, respectively.
