[Gate-users] Jaszczak SPECT Phantom modelisation

[Benoît Collette]

Hello,

I'm using GATE v. 4.0.0 and I'm trying to modelise a Jaszczak SPECT 
Phantom Deluxe ( http://www.biodex.com/radio/phantoms/phantoms_750.htm 
). The geometry I've created is very simple : a cylinder containing 
activity and, inside the cylinder, 6 spheres also containing activity. 
But, the execution is stopped and I receive error messages (see 
"testVG.output"). I think it's linked with the overlaping of the source 
in the cylinder and the sources in the spheres. But I don't know how to 
do this otherwise ...

Could somebody explain me how to define a source with a geometry like a 
cylinder extruded for the spheres ? Or how to do this otherwise with the 
version 4.0.0 ?

Thanks a lot.
