This study experimentally validates Monte Carlo-based proton dose calculation in the presence of the MF in a research version of the commercial TPS RayStation for MRiPT, using a measured three-dimensional (3D) magnetic vector field map of a 0.32 T in-beam MR scanner combined with a horizontal proton pencil beam scanning beam line.\n                    <jats:italic>Approach.<\/jats:italic>\n                    An MR-compatible mapping framework was used to acquire a high-resolution 3D magnetic vector field map, subsequently implemented into the TPS following coordinate transformations. Proton spot patterns and square radiation fields at 100, 150, and 220 MeV were delivered with and without the MF present. Dose distributions in air were measured using a 2D ionisation chamber array at multiple positions and compared with TPS dose calculations by analysing lateral beam shifts and field shape deformations with local\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mi>\u03b3<\/mml:mi>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    -analysis.
