From: Development of a bespoke phantom to optimize molecular PET imaging of pituitary tumors
Impact of TOF on reconstructed images. Representative images and line profiles for the normal pituitary phantom (A–C) and for phantoms containing tumors of different diameters with an activity ratio of 2:1 compared with the background gland (D–F, 2 mm; G–I, 4 mm; J–L, 6 mm). Key: AC, attenuation correction; PSF, point spread function; TOF, time of flight
