Abstract
The invention concerns a method for processing energy spectra of radiation transmitted by an object irradiated by an ionising radiation source, in particular X-ray radiation, for medical imaging or non-destructive testing applications. The method uses a detector comprising a plurality of pixels, each pixel being capable of acquiring a spectrum of the radiation transmitted by the object. The method makes it possible, based on a plurality of detected spectra, to estimate a spectrum, referred to as the scattering spectrum, representative of radiation scattered by the object. The estimation involves taking into account a spatial model of the scattering spectrum. Each acquired spectrum is corrected taking into account the estimated scattering spectrum. The invention makes it possible to reduce the influence of the scattering, by the object, of the spectrum emitted by the source.
