A combined registration-segmentation model for filtration estimation in the kidney

A. Zanna, E. Hodneland and E. Hanson

Abstract
In this talk we propose a combined registration-segmentation method for motion correction and parameter estimation for the kidney applied to dynamic contrast-enhanced MR images of the kidney. The motion correction is performed using normalized gradients as data term in the registration and a Mahalanobis distance from the segmented phases to a training set to supervise a segmentation. By applying this framework to input 4D image time series we conduct simultaneous motion correction and two-phase segmentation into renal cortex and background. The resulting time series are then used to estimate kidney perfusion.
