Paper Abstract

Ultra-low dose CT scanning produces non-ideal data with many problems when the number of photons reaching the detector is very small. One such problem is the bias introduced by clipping of negative measurement values prior to the log operation. This paper proposes a correction method for this clipping-induced bias, in particular for the case when access to the original un-clipped measurements is no longer available.
