Invertibility of Multi-Energy X-ray Transform
Yijun Ding, Eric W. Clarkson, Amit Ashok
Purpose: The goal is to provide a sufficient condition on the invertibility of a multi-energy (ME) X-ray transform. The energy-dependent X-ray attenuation profiles can be represent…
Inequalities and Approximations for Fisher Information in the Presence of Nuisance Parameters
Eric Clarkson
Many imaging systems are used to estimate a vector of parameters associated with the object being imaged. In many cases there are other parameters in the model for the imaging data…
Quantifying the Loss of Information from Binning List-Mode Data
Eric Clarkson
List-mode data is increasingly being uesd in SPECT and PET imaging, among other imaging modalities. However, there are still many imaging designs that effectively bin list-mode dat…
The Relation Between Bayesian Fisher Information and Shannon Information for Detecting a Change in a Parameter
Eric Clarkson
We derive a connection between performance of estimators the performance of the ideal observer on related detection tasks. Specifically we show how Shannon Information for the task…
Probability of Error for Detecting a Change in a Parameter, Total Variation of the Posterior Distribution, and Bayesian Fisher Information
Eric Clarkson
The van Trees inequality relates the Ensemble Mean Squared Error of an estimator to a Bayesian version of the Fisher Information. The Ziv-Zakai inequality relates the Ensemble Mean…
Fisher information analysis of list-mode SPECT emission data for joint estimation of activity and attenuation distribution
Md Ashequr Rahman, Yansong Zhu, Eric Clarkson +3
The potential to perform attenuation and scatter compensation (ASC) in single-photon emission computed tomography (SPECT) imaging using only the SPECT emission data is highly signi…
