[Gate-users] Issues on voxelized dose calculations for a phantom (using Hounsfield converter)

[Alex Vergara Gil]

Dear David

I have modified my macros and now I have a good patient dose image, so
I think Hounsfield Translator is free of bugs, I will try to put Air
as first segmentation material to see whats happens, but in the way I
am seeing this Hounsfield is far better approach for the problem.

I will update my templates to achieve this macro and when is ready I
will publish my results.
On issue #18 I put all my progress, This image was obtained with
geant4 10.1.1 + gate with all modifications of pull request #21
applied.

Regards
Alex
