Assessment of PTV Margins for Unity MR-Linac Treatments Using Cine-MRI Target Motion
In comprehensive motion management (CMM), Elekta Unity MR-Linac uses cine-MRI to monitor intra-fraction target motion. Due to the lack of efficient tools to determine patient-specific treatment margin, an isotropic GTV-to-PTV margin of 5 mm is used for all li...
