Integration of magnetic resonance imaging (MRI) in proton therapy (PT) has the potential to improve tumor-targeting precision. However, it is technically challenging to integrate an MRI scanner at the beam isocenter of a PT system due to space constraints and electromagnetic interactions between the two systems. We assessed the technical risks and challenges, and present a concept for the mechanical integration of a 0.5T MRI scanner (ASG MR-Open) into a PT gantry (IBA ProteusONE). Finite element simulations assess…
