Imaging detector with improved spatial accuracy

A detector array (112) of an imaging system (100) includes a radiation sensitive detector (202/204/206) configured to detect radiation and generates a signal indicative thereof and electronics (208) in electrical communication with the radiation sensitive detector. The electronics include a current-...

description	A detector array (112) of an imaging system (100) includes a radiation sensitive detector (202/204/206) configured to detect radiation and generates a signal indicative thereof and electronics (208) in electrical communication with the radiation sensitive detector. The electronics include a current-to-frequency converter (300) configured to convert the signal into a pulse train having a frequency indicative of a charge collected during an integration period. The electronics further include a residual charge collection circuit (322) electrically coupled to current-to-frequency converter. The residual charge collection circuit is configured to store charge collected by the integrator for an end portion of the integration period that does not results in a pulse of the pulse train, utilizing much of the electronics already in the current-to-frequency converter electronics.
