Quality assurance testing evaluation and comparison for magnetic resonance simulator and non-simulator magnetic resonance imaging modalities Public Deposited

Magnetic Resonance (MR) Imaging is imperative to radiation therapy (RT) treatment planning and is used to delineate tumor volumes and normal tissue structures. MR images are susceptible to many sources of significant geometric uncertainties that reduce the geometric fidelity of the image ultimately limiting its application in radiation medicine. The Magnetic Resonance Simulator (MR-SIM) has been shown to reduce setup related uncertainties and is approved for MR-only treatment planning in specific anatomical sites.4 8 Stricter Quality Assurance (QA) testing regimens and tolerance for an MR-SIM have recently been published by the American Association of Physicists in Medicine (AAPM) Task Group (TG) 284. Altered QA testing for an MR-SIM, as suggested by TG-284, has not been compared to that performed for a standard diagnostic MR system.
