Dosimetric feasibility of brain stereotactic radiosurgery with a 0.35 T MRI‐guided linac and comparison vs a C‐arm‐mounted linac

Purpose MRI is the gold‐standard imaging modality for brain tumor diagnosis and delineation. The purpose of this work was to investigate the feasibility of performing brain stereotactic radiosurgery (SRS) with a 0.35 T MRI‐guided linear accelerator (MRL) equipped with a double‐focused multileaf collimator (MLC). Dosimetric comparisons were made vs a conventional C‐arm‐mounted linac with a high‐definition MLC. Methods The quality of MRL...
