In this thesis we extended the mimicking algorithm to achieve automated robust proton treatment planning given a reference photon dose distribution for HNC patients.. More

In conclusion, we demonstrated that MCO-plans for HNC patients, created by novice dosimetry planners, result in IMRT plans with increased target dose uniformity and

Previously published multivariable NTCP models for grade 2-4 dysphagia and TFD were used for plan optimization (i.e. incorporated in the optimizer algorithm) and evaluation

The presented dose mimicking and dose reduction (DMR) algorithm automatically generates a robust MFO proton plan given a reference photon dose distribution and target and

In this study we assessed a margin-less approach to robust treatment planning using worst-case minimax robust optimization (RO) with and without a mid-treatment course plan

Figure 8.2b shows the dose distribution of a VMAT plan that was optimized with the hybrid objective function using log-transformed multivariable NTCP models for xerostomia, grade
