ABSTRACT:
A method of forming a light sensor array includes tuning a resistance level of a plurality of resistors. The resistors are included in a light sensor array for use with a positron emissision tomography (PET) scanner system. The light sensor array includes detection circuits that each includes one of the resistors connected in series with an avalanche photodiode.
