Title (EN) ENERGY-RESOLVED PHOTON COUNTING FOR CT
(FR) COMPTAGE DE PHOTONS A RESOLUTION D'ENERGIE POUR LA TOMOGRAPHIE PAR ORDINATEUR CT-
Abstract: front page image
(EN)Spectral CT systems require cheap detectors with high energy resolution. According to an aspect of the present invention, a computer tomography apparatus comprises a detector element which is segmented into a plurality of sub-pixels. Each sub-pixel has at least two thresholds and counting channels, wherein the second threshold for each sub-pixel varies over the nominal detector element. This may provide for an improved energy-resolved photon counting.
(FR)L'invention concerne des systèmes de tomographie par ordinateur CT- spectraux nécessitant des détecteurs bon marché à haute résolution en énergie. Selon un aspect de la présente invention, un appareil de tomographie par ordinateur comprend un élément détecteur qui est segmenté en une pluralité de sous-pixels. Chaque sous-pixel a au moins deux seuils et canaux de comptage, le deuxième seuil de chaque sous-pixel variant sur l'élément détecteur nominal. Cela permet d'obtenir un comptage de photons à résolution d'énergie amélioré.
