Dear Sebnem,

Yes, you can reproduce realistic spatial resolution and sensitivity with 
GATE. You can use the ECAT system, for example. In order to simulate 
realistic spatial resolution with GATE for PET scanner, usually you need 
to add some amount of blurring to the crystal identification. Please 
refer to the following section in the user's guide:

Digitizer and readout parameters / Digitizer modules /  Spatial blurring 
for PET

This module accounts for the degradation due to processes that are not 
explicitly simulated in GATE, like scintillation photon detection with 
PS-PMT.

For realistic sensitivity, do not forget to specify the energy 
resolution of your system, and possibly a global crystal quantum 
efficiency. Please refer to the following section in the user's guide:

Digitizer and readout parameters / Digitizer modules /  Crystal Blurring 
for a block detector


Regards,

Claude
