Abstract

This application describes an approach to filter, solely in the projection domain, correlated noise from (or de-noise) spectral/multi-energy projection data. As described herein, this can be achieved based at least on variances of the basis material line integrals and a covariance there between, based on multiple correlation coefficients and hyper-planes that describe the noise correlation between different basis material line integrals, and/or otherwise.
