Hi Gaters,
I make the phantom to calculate the image quality for PET: it have 6
spheres/clinders of diferents diameters, 4 hot sources of fluorine-18 and 2
cold sources.
The error that my program returned is the following:
*GateSourceMgr.cc (l.258): GateSourceMgr::CheckSourceName : ERROR : source
name <F18> already exists*
Can you help me?
how many times to define sources F-18? One for each sphere? *i.e.*, Four
sources?
The part of my code referred to particle sources is this:
