Robust treatment planning and evaluation
Proton therapy is more sensitive (less robust) to geometrical uncertainties when compared to photon radiotherapy. Various methods have been proposed to increase proton plan robustness. These methods include robust CTV-based planning as an alternative to conventional PTV-margin based planning. We focus on two aspects of robust treatment planning:
- to assess its performance when compared to photon therapy and
- to develop and evaluate methods for plan robustness evaluation.
