Hi,

I tried to simulate the SPECT system with GATE and I could visualize interactions in the detector. However, I would like to visualize source energy distribution too.

I tried to simulate a SPECT system and set up source as below:

/gate/source/addSource SourceConfinement

/gate/source/SourceConfinement/gps/type Volume

/gate/source/SourceConfinement/gps/shape Sphere

/gate/source/SourceConfinement/gps/radius 1.5 mm

/gate/source/SourceConfinement/gps/centre 0. 0. 0. mm

/gate/source/SourceConfinement/gps/particle gamma

/gate/source/SourceConfinement/gps/energy 140. keV

/gate/source/SourceConfinement/setActivity 740000. Bq

/gate/source/SourceConfinement/gps/angtype iso

I didn't mention any energy distribution here. So, what will be the actual energy distribution with this simulation and is there any way to plot the source energy distribution?
