Abstract
An imaging detector includes processing electronics (208) with a thermal coefficient about equal to a negative of a summation of thermal coefficients of a photosensor array (204) and a scintillator array (202) of the detector. In another instance, the imaging detector includes an A/D converter (302) that alternately converts first charge corresponding to impinging radiation into a first signal and second charge corresponding to decaying charge into a second signal and a logic unit (308) that corrects the first signal based on the second signal. In another instance, the imaging detector includes an A/D converter (302), an integrator offset voltage signal determiner (318), and a logic unit (308), wherein the determiner (318) induces an electrical current via an offset voltage, the A/D converter (302) measures the current, and the logic unit (308) calculates a resistance of the photosensor array (204) based on the reference voltage and the measured current.
