[Gate-users] positron range

[Samuel BURG]

Well, 

I'm not a ''king'' in positron range questions, but isn't 0.2 mm about the MEDIUM range and 0.43 mm about the MAX range in water for the 18-F positron ?

Best regards,

Samuel Burg

  1st question is ..
  During gate simulation, I found following error message
  Is it negligible?
  [GateTrajectoryNavigator::FindAnnihilationGammasTrackID]  WARNING : positron found and photonID vector size: 1
   
  2nd question is about the Positron range of F-18
  In the literature, positron range of F-18 was 0.2 mm at water
  However, I found that the positron range of F-18 was 0.43 mm at water in GATE simulation.
  What is the difference of that?
   
  Best regards
