[Gate-users] Dose Actor on Volume of Water

[Christopher Watanabe]

Hello fellow Gate Users,

I'm running simulations of a radioactive source placed within a volume of
water. Below I show snippets of showing the volume of water made inside a
world of air (3cm x 3cm x 3cm) and the dose actor.

I've played with the dose actor characteristics quite a bit, and I've found
that no matter what I do, the .mhd dose file output consistently shows a
Cube shaped dose distribution. This doesn't make sense to me, as I've
defined a spherical source of radiation and attached the dose actor to the
sphere of water...Can anyone suggest something that might be going wrong?
My source I define below:

Thanks a lot in advnance! I think if there's no problem with my dose actor
definition, then I must be doing something wrong with my source definition.

Best Regards,

Chris
