Characterizing magnetic field interactions between an in‐room MRI‐on‐rails and a radiotherapy linac: A comprehensive simulation and experimental study
This study developed and validated a comprehensive FEM-based simulation methodology to accurately characterize magnetic field interactions in a proximity-type MRI-guided RT system. The methodology mapped the MRI magnet's fringe field in both free space and as perturbed by the linac's ferromagnetic structure, with experimental data also supporting these findings. This robust framework offers a reliable tool for guiding engineering activities and defining safety bounds for system design.
