Title
(EN) DETECTOR CIRCUIT
(FR) CIRCUIT DE DÉTECTEUR
Abstract
(EN)
Some embodiments include an imaging system comprising a detector substrate, at least one detector circuit comprising a capacitor coupled with the detector substrate, the capacitor arranged to collect an electrical charge from the detector substrate, and the imaging system further comprises at least one programmable current source, arranged to provide a neutralizing charge to the capacitor, and the imaging system is configured to select a value for the neutralizing charge in dependence of a frame number.
(FR)
Dans certains modes de réalisation, l'invention concerne un système d'imagerie comprenant un substrat de détecteur et au moins un circuit de détecteur comportant un condensateur couplé au substrat de détecteur. Le condensateur est conçu pour collecter une charge électrique provenant du substrat de détecteur. Le système d'imagerie comprend en outre au moins une source de courant programmable, agencée pour fournir une charge de neutralisation au condensateur, et est conçu pour sélectionner une valeur pour la charge de neutralisation en fonction d'un numéro de trame.
