Abstract

The invention relates to a method for processing energy spectra of a radiation transmitted by an object irradiated by a source of ionizing radiations, in particular an X radiation, for applications in medical imaging or non-destructive inspection. The method implements a detector comprising a plurality of pixels, each pixel being able to establish a spectrum of the radiation transmitted by the object. The method makes it possible, from a plurality of spectra detected, to establish so-called corrected spectra. Each corrected spectrum is an estimation of the spectrum of a radiation, called primary radiation, transmitted by the object. The invention makes it possible to reduce the influence of the scattering, by the object, of the spectrum emitted by the source.
