[Gate-users] Regarding multiple detector / system output

[Beien Wang]

Hi GATE users,

I am studying a gamma detector's scintillation property using GATE. There
are two systems in my simulation: one is a SPECThead, the other one is an
OpticalSystem. The former one is to simulate the process of scintillation
in crystal. The latter one is used to see the distribution of the emitted
visible light from the scintillator.

What I want to get in output files are: 1. a binary/ascii file recording
the information about the interaction in the scintillator; 2. a projection
file recording the distribution of visible light in the back-layer of
scintillator.

The scintillator is attached with CrystalSD to detect gamma ray
interaction. The back-layer of the detector (a very thin layer of epoxy is
attached as a crystal) is also attached with CrystalSD to detect visible
light.

But, in the projection output file, only the gamma ray from SPECTHead
system is recorded not the visible light from OpticalSystem. This is not
what I want. I want to get the projection file from only OpticalSystem. I
wonder if there are anywhere I can customize from which systems the data
should be record in a multi-system in GATE. Thanks!

Best,
