[Gate-users] INTRINSIC RADIATION-LUTETIUM

[林 信宏]

Dear  Lorena,                       As Pietrzyk says,  there is  an example that I  refer to  this paper  "Validation of a GATE Model of Lu
Intrinsic Radioactivity in LSO PET Systems "                       FYI

Hi Lorena,



yes, you can indeed use GATE to simulate the Lu-176 Background
in LSO crystals. You have to place the Lu-176 defined as ion source
in a volume that covers the crystals and then confine the source
to the crystal volume.



Hope this helps!



Kind regards, 



Uwe Pietrzyk

Dear Gaters!



I'm doing simulations with a PET made ​​with LSO crystals.

My question is if there is any way, using GATE, to simulate the intrinsic radiation lutetium ?

Perhaps with a source of Lu or something else?



Thanks you all,



Lorena
