The October 4th the first stakeholder meeting of the MRgRT-DOS project was organized online. Representants from standards developing organisations, hospitals and manufacturers of MRgRT facilities and detector equipment participated in the meeting with the MRgRT-DOS consortium. The consortium presented the MRgRT-DOS project and the progress made so far. In the discussion session the knowledge gaps [...]
Recently several partners of the MRgRT-DOS consortium have published a review paper on reference dosimetry in MRI-linac beams. This paper is freely accessible via https://doi.org/10.1088/1361-6560/ab9efe
Following the succesful symposium organized in 2019 in Utrecht, DKFZ organizes a new symposium on dosimetry and QA in MR guided Radiotherapy prior to the MRinRT congress. Further information can be found on MRinRTHD2021 website.
Project I has been finalised Click here for the final publishable summary.
The MR linac simulator developed by University of Manchester is now available online via the following link. The simulator allows to mimick the effect of residual geometrical and dosimetrical uncertainties on clinical dose delivery.
