[Gate-users] Retrieving data about scattering in phantom

[Nicola Rizzi]

Hi Gaters,

I'm currently on my Bachelor final work: the simulation of NEMA-IEC Body
Phantom filled with Y90 microspheres. I have not designed PET/SPECT
acquisition equipment, so I have only the voxelized phantom and the sources
of Y90.

My question is: Is there a way to retrieve information about Compton
scattering in the phantom? I'm looking for the spectrum of photons that
have been scattered (secondaries) to compare with the spectrum of ones that
have not (primaries).

I tried attaching a Phase Space to the phantom and separate photons on the
basis of their Track ID, but this seems not to work. Does scattering change
Track ID?

Any kind of help is accepted,

Nicola Rizzi
