Purpose To validate the dosimetric accuracy of a commercially available magnetic
resonance guided intensity modulated radiation therapy (MRgIMRT) system using a hybrid
approach: 3-dimensional (3D) measurements and Monte Carlo calculations. Methods and
Materials We used PRESAGE radiochromic plastic dosimeters with remote optical computed
tomography readout to perform 3D high-resolution measurements, following a novel remote
dosimetry protocol. We followed the intensity modulated radiation therapy commissioning …
