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
