ABSTRACT:
A method and an apparatus are disclosed for processing of detector signals, for example in nuclear-medical imaging. In at least one disclosed embodiment, the signals from N photodetectors are transmitted to a total of approximately M=ld(N) output lines, with the signals from the photodetectors each being weighted with +1 or −1 for the addition onto an output line.
