  • Publication number: 20210364663
    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.

  • Publication number: 20210223189
    Abstract: A method for determining a response of a spectrometric system for measuring ionizing x-ray or gamma-ray photons, the measuring system comprising: a radiation source, configured to emit ionizing radiation along an emission axis; a pixelated detector, which comprises pixels, each pixel being configured to detect radiation emitted by the radiation source, and to acquire thereof an energy spectrum, in a plurality of energy channels; the emission axis being an axis extending between the radiation source and the detector; the response of the measuring system taking the form of effective spectra, defined for each pixel, and in each energy band, the effective spectrum of a pixel, in an energy band, corresponding to an energy distribution of the photons detected, by the pixel, in the energy channel, in the absence of any object interposed between the source and the pixel.
