MR-linacs have been implemented in the past with the capability to perform online adaptive radiotherapy. Because of the hybrid nature of an MR-linac, an adaptation of previous quality assurance (QA) procedures for conventional linacs is required in combination with new procedures for the imaging component.

Adaptive radiotherapy: The Elekta Unity MR-linac concept [PDF]
Clinical and Translational Radiation Oncology, 2019 The promise of the MR-linac is that one can visualize all anatomical changes during the course of radiotherapy and hence adapt the treatment plan in order to always have the optimal treatment. Yet, there is a trade-off to be made between the time spent for adapting the treatment plan against the dosimetric gain.

Towards adaptive IMRT sequencing for the MR-linac
Physics in Medicine and Biology, 2015The MRI linear accelerator (MR-linac) that is currently being installed in the University Medical Center Utrecht (Utrecht, The Netherlands), will be able to track the patient's target(s) and Organ(s) At Risk during radiation delivery. In this paper, we present a treatment planning system for intensity-modulated radiotherapy (IMRT).

The use of MRI in radiation therapy is rapidly increasing. Applications vary from the MRI simulator, to the MRI fused with CT, and to the integrated MRI+RT system. Compared with the standard MRI QA, a broader scope of QA features has to be defined in order to maximize the benefits of using MRI in radiation therapy.
