Title (EN) DYNAMIC FILTER FOR COMPUTED TOMOGRAPHY (CT)
(FR) FILTRE DYNAMIQUE POUR TOMODENSITOMÉTRIE
Abstract: front page image
(EN)An imaging system including a source (310) having a focal spot (406) that emits a radiation beam that traverses an examination region, a radiation sensitive detector array (316) having a plurality of pixels that detects radiation traversing the examination region and generates projection data indicative of the detected radiation, and a filter (314), disposed between the source and the examination region, that filters peripheral regions of the emitted radiation, wherein the filter includes two separate and moveable regions (402), each region having a substantially same thickness and constant homogeneity.
(FR)L'invention concerne un système d'imagerie comprenant une source (310) pourvue d'un foyer (406) émettant un faisceau de rayonnement qui traverse une zone d'examen, un réseau de détecteurs sensibles au rayonnement (316) pourvu d'une pluralité de pixels, qui détecte un rayonnement traversant la zone d'examen et génère des données de projection relatives au rayonnement détecté, ainsi qu'un filtre (314) disposé entre la source et la zone d'examen, qui filtre des zones périphériques du rayonnement émis, ce filtre comprenant deux zones mobiles distinctes (402), ces zones présentant sensiblement la même épaisseur et une homogénéité constante.
