Hi,

Thanks a lot for your advise.

But here I defined the shell by using "G4SubtractionSolid" to subtract the small inner ellipsoid from the outter one. I'm trying to simulate the situation in Cone-Beam Breast CT, with the breast model hanging in the air and the lateral side of the breast will be radiated with 1e6 phontons during the simulation. The shell is actually the breast skin that directly interact with the the emitted photons, from which I want to extract the information how many photons out of the 1e6 actually hit on the skin, which in other word is the out shell. That's why I did that by using the inner surface as G4PSSphereSurfaceCurrent did.

I'm not sure if the thought is feasible and very apperciated if any ideas you can provide.

Thanks, Linxi
