[Gate-users] Retrieving Fluorescence photon position of production

[BERGAMASCHI Antoine]

Hi all Gaters,

I am a beginner in Gate. I want to simulate self absorption phenomena in phantoms.
My goal is to produce a 3D map representing the position of production of each fluorescence photon hitting my photon detector.
I already tested using Actors and Filters on the phantom itself, which do work has a first "filter" but the result is acquiring the "total" fluorescence signal without self absorption.


My questions are:
- Is it possible to retrieve the position of creation of a given particle while only using the scripting tools available in gate. ( for example given a photon detected in a Volume "A", tell if its come from the primary source or any other Volume "X" )

- And if it is, what kind of strategy should i use to perform this.

Kind regards
