Claim:
1. A radiation detection device comprising: an optical detector pixel array having a plurality of pixel cells which can be triggered by optical photons; a plurality of pixel cell trigger state sensing circuits; at least a first current summing junction; wherein for at least a portion of the optical detector pixel array: each pixel cell is in communication with a pixel cell trigger state sensing circuit that is configured to generate a digital current signal having either a first predetermined amplitude indicative of a triggered pixel cell or a second predetermined amplitude indicative of a non-triggered pixel cell; wherein the first current summing junction is configured to receive the digital current signals from the plurality of pixel cell trigger state sensing circuits and to generate an analogue signal having an amplitude that corresponds to a real-time number of triggered pixel cells currently within the portion of the optical detector pixel array.
