Practical robustness evaluation in radiotherapy - A photon and proton-proof alternative to PTV-based plan evaluation
Background and purpose: A planning target volume (PTV) in photon treatments aims to ensure that the
clinical target volume (CTV) receives adequate dose despite treatment uncertainties. The underlying static dose cloud approximation (the assumption that the dose distribution is invariant to errors) is problematic in intensity modulated proton treatments where range errors should be taken into account as
well. The purpose of this work is to introduce a robustness evaluation method that is applicable to photon
and proton treatments and is consistent with (historic) PTV-base
