1. A method of determining a spectrum of energies of individual quanta of radiation received in a radiation detector, the method comprising the steps of:
(1) obtaining a time series of digital observations from the radiation detector comprising pulses corresponding to the detection of the individual quanta;
(2) computing spectrum sensitive statistics from the detector signal, the spectrum sensitive statistics defining a mapping from a density of amplitudes of the pulses to the spectrum sensitive statistics; and
(3) determining the spectrum by estimating the density of amplitudes of the pulses by applying an inversion of the mapping to the spectrum sensitive statistics.
