Title (EN) X-RAY DETECTOR IMAGING WITH POLYCHROMATIC SPECTRA
(FR) DETECTEUR D'IMAGERIE PAR RAYONS X AVEC SPECTRE POLYCHROMATIQUE
Abstract:
(EN) An x-ray detector has a sensor (24) absorbing x-ray quanta of polychromatic spectra and generating an electric sensor signal corresponding to the absorbed x-ray quanta. There is at least one counting channel (430) including a plurality of discriminators (420) each counting a number of charge signals (450) detected at a different respective threshold since a beginning of a measurement interval and an integrating channel (440) which measures overall charge of the charge signals detected since the beginning of the measurement interval.
(FR) L'invention concerne un détecteur de rayons X qui comprend un capteur (24) absorbant un quantum de rayons X à spectre polychromatique et générant un signal électrique de capteur correspondant au quantum de rayons X absorbés. Ce détecteur possède au moins une chaîne de comptage (430) comprenant une pluralité de discriminateurs (420) qui comptent chacun un certain nombre de signaux (450) de charge détectés à un seuil respectif différent à partir du début d'un intervalle de mesure, et une chaîne (440) d'intégration qui mesure la charge totale des signaux de charge détectés à partir du début de l'intervalle de mesure.
