Dose 2016

TPS, general limitations Anders A

Dose calculations bound to grids ( fluence map/phase space & dose voxel matrix)

– lack of beam data to drive dose calculations outside the largest field

Main TPS concern is planning dose to target (and saving nearby risk organ)

– Dose in the beam channel and penumbras modeled correctly…

– …scatter usually OK but…

– …less focus on accurate leakage outside of penumbra, far away scatter & neutrons

Peripheral dose considered as a radiation protection issue

– radiation protection management have a population/class solution oriented context

– TPS designed for individual patient contexts
