ABSTRACT:
A method for identifying PMT drift in an edge PMT of a gamma camera, where said gamma camera includes a plurality of PMTs arranged in an array. The central point of said array generates an intensity signal M during a flood procedure and a field of view edge blocks a portion of the edge PMT. The PMT intensity profile changes due to the blocked PMT portion and contains a first point at which the intensity level is N, where N is a fraction of M.
