title = "X-ray measurement model and information-theoretic metric incorporating material variability with energy correlations",
abstract = "Extending our prior work, we propose a multi-energy X-ray measurement model incorporating material variability with energy correlations to enable the analysis and exploration of the performance of X-ray imaging and sensing systems. Based on this measurement model we provide analytical expressions for the Cauchy-Schwarz mutual information (ICS) measure that quantifies the performance limits of an X-ray measurement system for the threat-detection task. We analyze the performance of a prototypical X-ray measurement system to demonstrate the utility of our proposed material variability measurement model.",
