Magnetic field effects on particle beams and their implications for dose calculation in <scp>MR</scp>‐guided particle therapy

Abstract

Non-negligible dose deformations at the Bragg peak area were identified for high initial energies and strong magnetic fields. A fast numerical algorithm based on the solution of the energy-corrected relativistic Lorentz equation was able to describe the beam path, taking into account the particle energy, magnetic field, and material.
