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

[Albert Grace Lieu]

Dear Gate users and developers,

There are a couple of papers [1
<https://aapm.onlinelibrary.wiley.com/doi/abs/10.1118/1.4824694>,2
<https://ieeexplore.ieee.org/document/5751205>] 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.
