[Castor-users] Cherenkov Photons vs cylindricalPET vs CASToR with TOF vs CASTor without TOF....

[Simon Stute]

Hi,

You will have to modify the tool for GATE conversion to CASToR, in order 
to write the TOF information for each event.
Page 33, you will find the specifications of a CASToR list-mode event, 
you will have to write the TOF information at the right position.

If you added a time blurring module in GATE, then you can directly write 
the difference in time arrival of the two singles.
If you did not, you will have to add that stochastic time blurring for 
each of the two singles of each coincidence in the conversion tool.

Also as you simulate the cherenkov photons to make GATE singles, beware 
of what is the time actually written in the ROOT file (I do not know 
what GATE does); is it the first photon, the integration time of all 
photons, etc.

Best
Simon
