[Gate-users] Fluence Actor

Hi,
I think that this is meant to be used in combination with
GateScatterOrderTrackInformation. Every time an interaction occurs in the
volume to which GateScatterOrderTrackInformation is attached, this
information will be added to a user structure of the particle track. When
recording the fluence with the GateFluenceActor, it will check the same
structure of the particle and record the particle in separate images. This
has been developped to measure the amount of Compton vs Rayleigh scatter
and I think it currently works for photons only since only Compton,
Rayleigh and Fluorescence are tracked.
I hope this helps,
Simon
