Fig.2 DVH for the TG119 phantom, prostate, brain and liver patients. Results are displayed for B = 0T (solid lines) and B = 1T (dashed lines). Conclusion The in-house developed PB model implemented in the research TPS matRad provides highly accurate dose distributions for protons in transverse magnetic fields for homogenous phantoms and exemplary treatments. More complex benchmarking studies are foreseen to identify the limits of applicability of the proposed model.
