Dosimetric validation of proton beam deflection and field shape deformation in a measured transverse magnetic field of an in-beam MR scanner using a novel dose calculation functionality in a research version of a commercial treatment planning system
Objective. Integrating in-beam magnetic resonance imaging (MRI) with proton therapy (PT) introduces magnetic fields (MFs) that affect proton beam transport and therefore require accurate incorporation into the treatment planning system (TPS) for magnetic resonance (MR)-integrated PT (MRiPT). This study experimentally v...
