[Gate-users] PET simulation:Compton scatter events in coincidence output

[Marc Chamberland]

Hi Imre,

Any number of things could be wrong with your simulations (or it could be a rare bug), but it would be easier if you sent the macros you are using and told us which version of Gate you have. ;)

Hi everyone,

I have a problem with the coincidence output.
I would like to get information about the Compton scatter interactions of gamma photons in the simulated phantom volume. Basically the coincidence output data separately contain the number of Compton interaction of the gammas in the phantom and the crystal.
I simulate a very large phantom so I should get lot of scatter events.
However, I get zero Compton events in the phantom.

Could anyone help me?

Thanks,
Imre
