LIKELIHOOD BASED SPECTRAL DATA PROJECTION DOMAIN DE NOISING

摘要

A method for processing projection data in the projection domain includes receiving the projection data. The projection data is generated by a spectral detector and includes two or more independent energy resolved measurements in which at least one of the two or more measurements has first photon statistics. The method further includes generating a de noised measurement in electronic format for the at least one of the two or more measurements having the first photon statistics. The de noised measurement has second photon statistics which are better than the first photon statistics.
