[Gate-users] How to simulate Lu-176 in LSO crystal

[Maxime Toussaint]

Greetings,

I have never used it but I have heard one of my colleague say that this could be done with the Noise module of the Digitizer.

About your approach, I would guess that the only detector named "Crystal" in your system would be the first one created, the one that is repeated. The ones created by the repeater most likely have an automatic generated name but I have no idea what it is. Even if you had the name of each one, you would need to add a source to each one which would be complex (I think?).

Bests,
Maxime Toussaint

Dear Gate users and developers,

There are a couple of papers [1<https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Faapm.onlinelibrary.wiley.com%2Fdoi%2Fabs%2F10.1118%2F1.4824694&data=02%7C01%7Cmaxime.toussaint%40usherbrooke.ca%7C5a63bc4be9ae4335ee9008d80dc5af21%7C3a5a8744593545f99423b32c3a5de082%7C0%7C0%7C637274490000985547&sdata=z25mHQ3vAeaiCVrSk%2BHuajOruDFHzil61wO6v5uptPE%3D&reserved=0>,2<https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fieeexplore.ieee.org%2Fdocument%2F5751205&data=02%7C01%7Cmaxime.toussaint%40usherbrooke.ca%7C5a63bc4be9ae4335ee9008d80dc5af21%7C3a5a8744593545f99423b32c3a5de082%7C0%7C0%7C637274490000995545&sdata=fGxaotiPFDWbMjYO9uyoQVV%2BgIhTi%2BKLBvaHH3aau6k%3D&reserved=0>] addressing the importance of adding the simulation of Lu-176 in Lutetium based crystal in GATE simulation. I try to do this to my simulated PET system that has thousands of pieces of crystals (created with linear and cubic array repeater). My general idea of implementing this is to create a Lu176 ion source and then attach it to my crystals. However,  when I do:

/gate/source/Lu176/attachTo Crystal

the Lu176 is only attached to a single piece of crystal (which can be visualized with /gate/source/Lu176/visualize 1000 red 3).  Has anyone implemented this before? Could you please share your thoughts?

Thanks a lot. Greatly appreciated.
