QA of MR-linac

, 2023
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.

The Quality Assurance of a 1.5 T MR-Linac [PDF]

Seminars in Radiation Oncology
The recent introduction of a commercial 1.5 T MR-linac system has considerably improved the image quality of the patient acquired in the treatment unit as well as enabling online adaptive radiation therapy (oART) treatment strategies. Quality Assurance (QA) of this new technology requires new methodology that allows for the high field MR in a linac ...

Dosimetry for the MR-linac [PDF]

, 2015
The purpose of this thesis is to investigate the inuence of the MR scanner on dosimetry for the radiation modality, and to investigate the possible solutions for the dosimetric measurements discussed in section 1.7. Chapter 2 investigates the feasibility to use a standardized national reference dosimetry protocol for the MR-linac.

Patient expectation and experience of MR-guided radiotherapy using a 1.5T MR-Linac [PDF]

Technical Innovations & Patient Support in Radiation Oncology
Background and Purpose: Online adaptive MR-guided radiotherapy (MRgRT) is a relatively new form of radiotherapy treatment, delivered using a MR-Linac. It is unknown what patients expect from this treatment and whether these expectations are met.
