Abstract
A detector tile () of an imaging detector array () includes a scintillator array (), a photosensor array (), which includes a plurality of photosensitive pixels, optically coupled to the scintillator array (), and a current-to-frequency (I/F) converter (). The I/F converter () includes an integrator () that integrates charge output by a photosensitive pixel during an integration period and generates a signal indicative thereof and a comparator () that generates a pulse when the generated signal satisfies predetermined criteria during the integration period. A reset device () resets the integrator () in response to the comparator () generating a pulse. Circuitry () samples the generated signal at a beginning of the integration period and/or at an end of the integration period and generates quantized digital data indicative thereof. Logic () estimates the charge at the input of the integrator () based on the generated digital data.
