hi everyone
how do i define timing window in PET?
Hi. Maybe a way is through the global time, which is counted from the generation of a primary particle. I hope this helps you.
hi, Thank you very much for replying 
Hello!
Indeed, the global time is your answer.
I’m assuming your primary generator action is simultaneously emitting two oppositely oriented 511keV gamma rays?
You’ll just need to record the global time when both gamma rays are detected.
Happy coding!
