An ESTRO-ACROP guideline on quality assurance and medical physics commissioning of online MRI guided radiotherapy systems based on a consensus expert opinion

“…It is recommended to test general MR image quality such as slice position and thickness accuracy, the high and low contrast resolution and the detectability of objects on low contrast images [5,8] on a monthly basis. Vendor-provided QA methodology is recommended [9].…”

“…The magnetic field of a MR Linac can create dangerous situations that can seriously injure a person, damage the system or cause interference in the measuring equipment [4,5,[42][43][44]. Therefore, screening protocols to ensure that devices are MR safe must be in place for clinical practice.…”

“…There are several guidelines on quality assurance (QA) and commissioning of computed tomography (CT) guided radiotherapy systems [1][2][3] and of MR scanners used for diagnostics as well as in radiotherapy treatment planning [4][5][6][7][8]. However currently there are no cross-platform guidelines on commissioning and quality assurance for oMRgRT systems.…”

“…Whereas projectile hazards pose the most severe threat to patients and staff, thermal injuries to patients pose the most likely and frequent hazard. 3 Fully protecting patients from burns has proven elusive. The new document strengthens three key points: preventing skin-to-skin contact points, preventing contact between the patient and the magnet cover surface, and changing all patients into known MR Safe gowns or scrubs supplied by the facility.…”
