[Gate-users] 2 Head PET

[José Ramos]

Dear GATE users:
Actually I'm try to simulate a two head PET for small animals, I'm using an
array of 20x20 crystals with dimensions 2.4x2.4x10mm3, the distance between
the opposite detector heads is 80mm and the septal distance is 0.2mm. My
problem is that I can't obtain coincidences, my coincidence time window is
10 ns and the source is F18 e+. Does anybody what's happen?
Best regards
