Amsterdam, The Netherlands

In-room MRI-guided RT

Online webinar: kick-off event on 7 October 2021

As from 7 October pre-recorded lectures will be available for participants to study at their own pace prior to the live Q&A sessions in Amsterdam. The pre-recorded lectures will be available from ESTRO Moodle.

Live module: 3 day course from 7 to 9 November 2021, Amsterdam, The Netherlands

This blended course is aimed at all professionals in the field of radiation therapy: radiation oncologists (ROs), medical physicists (MP) and radiation therapists (RTTs). In order to encourage teamwork, participation of multidisciplinary teams belonging to the same institute is encouraged, but not mandatory.

The course is intended for participants who are either directly involved in a clinical MR-guided RT project, or who want to update their knowledge on this topic.

The recent technological development in Image Guided Radiotherapy has led to the introduction of new hybrid machines linking an MRI scanner to a linear accelerator. The possibility to have high soft tissue contrast with no extra dose to the patient and live imaging to gate the treatment delivery open new frontiers in the world of adaptive radiotherapy. The complexity of this new discipline requires advanced skills in the fields of physics and radiotherapy.

In this interdisciplinary course, we aim to:

- Provide a detailed overview of the clinical rationale and indications of in-room MRI-guided RT;

- Deepen the knowledge of the clinical, physical and technical aspects of MRI-guided RT

implementation in clinical practice;

- Share opportunities and challenges of the MRI-guided radiotherapy sytems in different clinical scenarios.

Learning Outcomes

By the end of this course participants should be able to:

  • Understand the technology underlying the hybrid MR Linac system, discussing the differences between high and low magnetic field machines
  • Appreciate the clinical rationale of in room MRI-guided RT and its possible applications in the frame of modern IGRT
  • Understand the clinical workflow of an in-room MRI-guided RT treatment and the role of all the involved professionals
  • Become familiar with the most innovative online adaptive radiotherapy approaches
  • Identify the most appropriate patients positioning solutions
  • Appreciate the different planning strategies of MRI-guided RT
  • Become familiar with patients selection criteria and MRI safety issues.

Course Content/Programme

  • Online adaptive radiotherapy: workflow and criticalities
  • RT and MR safety
  • Dose Accumulation

Course Design

The course will take place over a 5 weeks period and will be delivered using a blended learning approach, i.e. a combination of recorded online seminars, live teleconferencing and face-to-face teaching:

  • The theoretical components will be delivered using the ESTRO Moodle, the ESTRO Virtual Learning Environment (VLE), where recorded seminars will be available for participants to join at a time that suits them.
  • Additionally, live teleconference tutorials will also take place to provide participants with the opportunity to discuss their learning to date with the teachers and peers.

The face-to-face component of the course will occur over a three-day period in Amsterdam and mainly consists out of summaries from the recorded lectures with Q&A, workshops where clinical cases treated by in-room MRI-guided RT radiotherapy will be discussed, group discussions of the assignments per discipline and multidisciplinary.

For the updated calendars please consult the ESTRO website page of this course.


Defined for each of the disciplines, basic knowledge of radiation oncology, radiation physics and magnetic resonance imaging are prerequisites.

Teaching Methods

  • 5 hours of online lectures
  • 4 hours of live teleconference tutorials
  • 1 practical course of 3 days with workshops
