Description
Kerryn Brown and colleagues check a dose snag when breast radiotherapy is delivered face-down on an MR-Linac machine. Their 2026 technical note covers three patients with left-sided breast cancer treated prone, where the breast unavoidably touched the couch. Partial breast treatment gives a higher dose to a smaller volume, and the magnetic scanner-linac sees soft tissue superbly, but its narrow bore forces the contact in question.
Plans delivered 30 Gy in five fractions and were recalculated with and without the magnetic field to isolate its effect. Dose to the whole skin layer ran consistently higher with the field on, and the contact patch of skin was scored separately. All plans still met target and safety limits, giving planners numbers for a quirk of the prone setup.
