A technique that determines optimal rod window width for rotating rod transmission studies in positron emission tomography (PET) is discussed. Rod windowing reduces noise in rotating rod transmission studies. Lines-of-response (LOR) which intersect the rods generate primarily true coincidence events. LORs which pass far from the rods generate random and scatter events. Since the angular position of the rotating rods is known in real-time, LORs, which produce mostly noise are gated off.<<ETX>>
