[Gate-users] correction of randoms

[phy phy]

Hi dear users Gate

I have simulated a clinical PET that uses LSO crystals.
I want to get the NECR parameter, so I need randoms, scatters and trues
rates.
I set the phantom and activity according to NEMA. The values of the true
and scatter rates are obtained according to the experimental results, but
the random values are very high.
Is there a correction for the random rates?
Please tell me how to make this correction in the simulation.

I appreciate any help in advance.
