Hi Lorena,<br>
<br>
yes, you can indeed use GATE to simulate the Lu-176 Background<br>
in LSO crystals. You have to place the Lu-176 defined as ion source<br>
in a volume that covers the crystals and then confine the source<br>
to the crystal volume.<br>
<br>
Hope this helps!<br>
<br>
Kind regards,<br>
<br>

Dear Gaters!<br>
<br>
I'm doing simulations with a PET made ??with LSO crystals.<br>
My question is if there is any way, using GATE, to simulate the intrinsic radiation lutetium ?<br>
Perhaps with a source of Lu or something else?<br>
<br>
Thanks you all,<br>
<br>
