Reducing the set of considered scenarios in robust optimization of intensity-modulated proton therapy
Ivar Bengtsson
Robust optimization is a commonly employed method to mitigate uncertainties in the planning of intensity-modulated proton therapy (IMPT). In certain contexts, the large number of u…

Dosimetric impact of real-time re-optimization of proton pencil-beam scanning for moving targets
Ivar Bengtsson, Anders Forsgren, Albin Fredriksson
When treating moving tumors, the precise delivery of proton therapy by pencil beam scanning (PBS) is challenged by the interplay effect. Although several 4D-optimization methods ha…

Interplay-robust optimization for treating irregularly breathing lung patients with pencil beam scanning
Ivar Bengtsson, Anders Forsgren, Albin Fredriksson +1
The steep dose gradients obtained with pencil beam scanning allow for precise tumor targeting at the cost of high sensitivity to uncertainties. Robust optimization is commonly appl…
