The invention relates to a method for the treatment of energy spectra of radiation transmitted by an object irradiated by a source of ionizing radiation, in particular X-ray radiation, for applications in medical imaging or non-destructive testing. The method uses a detector comprising a plurality of pixels, each pixel being able to acquire a spectrum of the radiation transmitted by the object. The method makes it possible, from a plurality of detected spectra, to establish a spectrum, called scattering spectrum, representative of a radiation scattered by the object. Each acquired spectrum is corrected by taking into account the diffusion spectrum thus established. The invention makes it possible to reduce the influence of the diffusion, by the object, of the spectrum emitted by the source. |
