[Gate-users] About how to use Na22 as the source

[Michaela Gaens]

Hi,

I'm guessing you checked the energy spectrum to look for the third gamma? Just taking a quick look at your macro I think you are not seeing it because you limit the energy window for your singles to 800 keV. This way  events from the 1275 keV gamma will not be stored in your output file.

Best regards,
Michaela

Hi,

For people to help you, you should tell the mailing list how you determined that it is not producing the gamma ray.

Cheers,
Marc

Hello everyone:
I am using gate v6.2 for the simulation of our PET system, and want to
use Na22 as the source. My code is in the attachment. It seem not to
produce the Gamma. I do not know whether there is something wrong with
my source or my physical process. Could anyone send me a complete
instance with Na22 as the source? Thanks a lot! Best!
