Among other things, one or more techniques and/or systems are described for resetting an integration circuit (206) of a detector cell or an electronics arrangement (200) thereof. When a voltage signal output by the integration circuit (206) exceeds a specified threshold (e.g., indicating that a specified number of radiation photons have been detected), a charge injection circuit (208) is configured to inject charge into the integration circuit (206). The injected charge is typically opposite in polarity to stored charge that is stored by a capacitor (214) of the integration circuit (206) and is configured to counteract the stored charge. In this way, a voltage potential at the capacitor (214) decreases, causing the voltage signal output by the integration circuit (206) to decrease. Moreover, a number of resets per measurement interval may be recorded to determine an average current output by a radiation detection element of the detector cell over the measurement interval to facilitate acquiring photon integration readings. |
