A radiation device includes a detector connected to a multi-functional radiation identifying and processing application specific integrated circuit. The detector includes a plurality of individual imaging cells, each imaging cell generating a charge in response to incident radiation events and outputting the generated charge at an imaging cell output. The application specific integrated circuit includes a different circuit connected respectively to a corresponding one of the imaging cell outputs, each circuit receiving and processing the generated charge received from the corresponding one imaging cell output. Each circuit includes a preamplifier for generating a voltage or current amplitude in response to the received charge, a counter, and a mode logic configured for setting the counter to perform, selectively, at least two of a) photon counting, b) analog to digital conversion of the one of the voltage amplitude and the current amplitude, and c) timing measurement of incident radiation events.
