[Gate-users] Hits.dat question simplified

[Marcin Balcerzyk]

Hi Gaters and Uwe.

 

I have a question to Hits.dat ascii file produced in PET scanner simulation.
Below is the image of the table taken from Hits.dat. In two last rows are
data for photoelectric event in high density material like LSO with Lu atom.

 



 

You can see that stepLength for photoelectric event is 8.5 mm, which for a
63 keV photon in LSO is highly unlikely. My question is what does step
length associated with first hit in the crystal really correspond to? Is it
a path in the crystal until the photoelectric event, so the step length is
counted only within crystal which is in my case a sensitive detector?

 

Regards
