Title (EN) X-RAY GENERATOR OUTPUT REGULATION
(FR) RÉGULATION DE SORTIE DE GÉNÉRATEUR DE RAYONS X
Abstract:
(EN) The techniques and device provided herein relate to regulating a source generator in an X-ray based equipment. In particular, an X-ray system is provided that comprises an X-ray generator and a reference detector system that regulates the output of the X-ray generator. The reference detector system comprises a direct channel that allows at least a portion of the photons to directly reach the detector crystal and a plurality of fluorescent channels, such that photon flux entering the reference detector from the fluorescent channels is negligibly impacted by variations of beam spots, shapes and/or positions.
(FR) L'invention concerne des techniques et un dispositif se rapportant à la régulation d'un générateur de source dans un équipement à rayons X. En particulier, un système de rayons X comprend un générateur de rayons X et un système de détecteur de référence qui régule la sortie du générateur de rayons X. Le système de détecteur de référence comprend un canal direct qui permet à au moins une partie des photons d'atteindre directement le cristal de détecteur, et une pluralité de canaux fluorescents, de telle sorte qu'un flux de photons entrant dans le détecteur de référence depuis les canaux fluorescents est peu affecté par des variations de points, de formes et/ou de positions de faisceau.
