Question Physics List for Medical Application 

Forum: Physics List
Date: 19 Aug, 2013
From: Constantin Csato <Constantin Csato>

Good afternoon,

In our workgroup we are working with a thin silicon foil with a thickness of 10Ám. It is possible that the foil proves useful as a passive scattering element, like it is already used in proton therapy and carbon ion therapy. Such a filter is known as a ridge filter.

As a first step I would like to evaluate, in what way the foil modifies the depth dose distribution and lateral distribution. For this first step I chose a simplified simulation set up.

Simulation set up:

Plane source Carbon Ion/Proton Energy: 80-160MeV

Silicon Foil 10Ám thickness
|

Water target/voxelized Phantom

I am unsure as to what PhysicList to choose for carbon ion and protons in an energy range of 80-160MeV. Another point is that the foil is rather thin and I wonder if it is necessary to reduce the step size or modify the productions cuts. What would you recommend from your experience?

I would very much appreciate any comments and help!

Kind regards,

Constantin
