[Gate-users] Time of flight

[Tahereh Niknejad]

Dear Gate users,

I want to study the time of flight PET with Gate output.
But, the time of photons detection in the root output is with 6 digits
after the decimal point. therefore, time 1 and time 2 are exactly the same,
even if the source is not in the middle and around 1000 meter is needed to
have the time difference between two photons in coincidence.

Is there any advice how can I get the time difference?

Best regards,
Tahereh
