FIELD: physics, computer engineering.
SUBSTANCE: invention relates to generation of spectrum images and can be used in CAT. Spectral processor is designed to process detector signal describing polychromatic radiation detected imaging system. Said processor comprises: first processing channel to generate first spectral signal derived from detector signal. Note here that said first spectral signal comprises first spectral data on detector signal. Processor second processing channel generate second spectral signal derived from the AC component of said detector signal. Note here that said second spectral signal comprises second spectral data on detector signal. Note here that first and second spectral signals are used for spectral decomposition of detector signal.
EFFECT: higher spectrum resolution.
