| description | Disclosed is a method for modelling a distorted energy spectrum in a multi-energy x-ray CT imaging system using probability distribution functions, the method including taking open beam measurements across a range of fluxes, estimating true interaction rates from said fluxes, calculating the probabilities of photons being counted, pileup order, and counts recorded to produce a model of the distorted energy spectrum. Also described are computer implemented methods and systems for modelling distortions and optimizing material images produced from multi-energy x-ray CT scanning systems using the modelling techniques. |
