Abstract
An imaging detector includes processing electronics with a thermal coefficient about equal to a negative of a summation of thermal coefficients of a photosensor array and a scintillator array of the detector. In another instance, the imaging detector includes an A/D converter 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 that corrects the first signal based on the second signal. In another instance, the imaging detector includes an A/D converter, an integrator offset voltage signal determiner, and a logic unit, wherein the determiner induces an electrical current via an offset voltage, the A/D converter measures the current, and the logic unit calculates a resistance of the photosensor array based on the reference voltage and the measured current.
