Abstract

A radiation sensitive detector array (112) includes a photo sensor (204) that detects a photon and generates a signal indicative thereof. The radiation sensitive detector array (112) also includes a signal analyzer (214) that energy bins and counts the signal when the signal analyzer (214) is able to identify the signal in the output of the photo sensor (204), and that integrates the output of the photo sensor (204) over an integration period when the signal analyzer (214) is not able to identify the signal in the output of the photo sensor (204).
