we used the GATE code to simulate a dual-head positron emission mammography(PEM) system using LYSO detectors and evaluate its performances.The NEMA NU 4-2008 standard
modified slightly
was referred for the PEM system.System performances of sensitivity
phantom scattering
crystal scattering
counting rate and intrinsic spatial resolution were simulated.A peak absolute sensitivity of 14.17%
intrinsic spatial resolution of 1.2 mm and the peak NEC rate of 1.508×105/s at an activity of 29.6 MBq in a breast phantom were found at a 350–650 keV energy window and 6 cm detector separation
