Magnetic resonance imaging (MRI) provides excellent soft-tissue visualization, thereby increasing the sensitivity for detecting tumor and normal tissue boundary. Recently, hybrid MR scanners and linear accelerators (MR-Linac) have been developed, including the MRIdian (ViewRay, Oakwood, USA) and Unity (Elekta, Stockholm, Sweden). This article explained the MR-linac system and related medical imaging research.
