      abstract     = {With the rapid increase in clinical treatments with
                      MRI-linacs, a consistent, harmonized and sustainable ground
                      for reference dosimetry in MRI-linacs is needed. Specific
                      for reference dosimetry in MRI-linacs is the presence of a
                      strong magnetic field. Therefore, existing Code of Practices
                      (CoPs) are inadequate. In recent years, a vast amount of
                      papers has been published in relation to this topic. The
                      purpose of this review paper is twofold: to give an overview
                      and evaluate the existing literature for reference dosimetry
                      in MRI-linacs and to discuss whether this literature and
                      datasets are adequate and complete to serve as basis for the
                      development of a new or to extend existing CoPs. This review
                      is prefaced with an overview of existing MRI-linac
                      facilities. Then an introduction on the physics of radiation
                      transport in magnetic fields is given. The main part of the
                      review is devoted to the evaluation of the literature with
                      respect to the following subjects: • beam characteristics
                      of MRI-linac facilities; • formalisms for reference
                      dosimetry in MRI-linacs; • characteristics of ionization
                      chambers in the presence of magnetic fields; • ionization
                      chamber beam quality correction factors; • ionization
                      chamber magnetic field correction factors. The review is
                      completed with a discussion whether the existing literature
                      is adequate to serve as basis for a CoP. In addition, it
                      highlights subjects for future research on this topic.},
