A technique determines the optimal rod window width for rotating rod transmission studies in positron emission tomography VEX). Rod windowing reduces noise in rotating rod transmission studies. Lines-of-response (LOR) which intersect the rads generate primarily true coincidence events. LOR which pass far from the rods generate random and scatter events. Since the angular pasition of the rotating rods is known in realtime, LOR which produce mostly noise are gated &.
