Question voxelized source activity 

Forum: Medical Applications
Date: 15 Mar, 2012
From: Clare Huang <Clare Huang>

Hi all,

I have been looking for ways to define voxelized source in a user-defined voxelized geometry. I have found numerous posts on this forum asking the same question, but no response was found. I was wondering if this is either a quite trivial task, or something that I am missing.

Just brainstorming here...from my understanding of geant4 as of now, here is what one can define a voxelize source, in the class definition of PrimaryGeneratorAction,

(1) create a text file with source intensity and position for all the source voxels (2) for-loop over all voxels to add the source with its intensity and position; do you define a point source (e.g. particleGun or a particleSource) for each source voxel?

let me know if this is a feasible way to approach this task or if there's other more eloquent way to approach this task.

thanks a lot for your time and help in advance!

Best regards, Clare
