[Gate-users] (no subject)

Hello dear Gaters,


I am using GATE v5 on Fedora and I want to create a phantom uniformely filled with water and F18. So I called the CylinderF18 model source and filled it with the apropriate activity. I am doing counts rates study and the number of prompt is much larger than in my experiment. the volume of this cylinder is approximatively 5 L encapsulated in an empty plexiglass cylinder. I analyze random trues and prompts with the (modified) program benchmarkPET.C. Now I have a doubt about the activity, should put it in MBq/mL or MBq only?
Another point about benchmarkPET.C , in the loop where coincidences are sorted one can find runID=0 or runID=1> Do you know what these runs mean? 

Thank you for any help.
Cheers
