Physics for Modern Radiotherapy (a Joint Course for Clinicians and Physicists) (ONLINE COURSE, starting 7th September 2020)

Online Course

Registration by email: 10 July-3 August

Kick-off with welcome and introduction at 12:50 on 7. of September. End of course on 10. of September at 17:30pm. Pre-recorded lectures will be available 2 weeks prior the course. 


The course is primarily aimed at: 

  • Trainees in radiation oncology or radiation physics 
  • Radiation oncologists and medical physicists early in their career

The course is also suitable for

  • Clinicians and physicists that are eager to update their knowledge on physics and technical aspects of radiotherapy.
  • Dosimetrists and radiation technologists having a strong interest in the application of physics and technology in radiotherapy.
  • PhD students in radiation therapy or physics.

As the focus is on clinical application, the teachers’ team consists of both radiation oncologists (50%) and medical physicists (50%). 

Course Directors

  • Ben Heijmen, Medical Physicist, Erasmus MC - Cancer Institute, Rotterdam (NL)
  • Eduard Gershkevits, Chief medical physicist, North Estonia Medical Centre, Tallinn (EE)


  • Silvia Molinelli, Medical Physicist, Fondazione CNAO, Pavia (IT)
  • Shaista Hafeez, Clinical Oncologist, Royal Marsden NHS Trust and The Institute of Cancer Research, Marsden (UK) 
  • Tom Depuydt, Medical Physicist,  University Hospital Gasthuisberg, Leuven (BE) 
  • Michael Gubanski, Radiation Oncologist, Karolinska University Hospital – Sodersjukhuset, Stockholm (SE)
  • Milan Tomseij, Medical Physicist, CHU Charleroi, Hôpital André Vésale, Montigny-le-Tilleul (BE)
  • Louise Murray, Leeds Teaching Hospitals NHS Trust, UK
  • Stephanie Peeters, Maastro, NL UK

The lectures aim to: 

  • Provide knowledge and understanding of physics relevant to modern clinical radiotherapy 
  • Provide comprehensive overviews of imaging and volume concepts in radiotherapy 
  • Discuss modern dose delivery techniques, such as IMRT, rotational therapy (VMAT, helical tomotherapy), S(B)RT, IGRT, adaptive therapy (ART), particle therapy and brachytherapy 
  • Discuss safety issues in lectures on commissioning and QA/QC, radiation protection, in vivo dosimetry and induction of secondary tumours.

Complimentary to the lectures, this course has clinical case discussions as an important component. The case discussions aim at teaching physics by practical application in treatment planning.

Learning Outcomes

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

  • Discuss and select modern treatment techniques based on their pros and cons
  • Select physics and technical measures that enhance effective and safe application of radiation therapy.

Course Content

1. Lectures on:

  • IMRT/VMAT - physics aspects, clinical application and impact
  • Stereotactic radiotherapy (cranial and extra-cranial)
  • Rotational therapy (VMAT, helical tomotherapy)  
  • Particle therapy (electrons, protons, ions)
  • Volumes in external beam radiotherapy Imaging for GTV definition
  • Imaging for GTV definition
  • Imaging for treatment preparation and planning
  • PTV margin calculation
  • IGRT (equipment for in-room imaging, set-up correction strategies, clinical examples)
  • Adaptive radiotherapy
  • Dose prescription and plan evaluation
  • Field junctions (how, when, and alternatives)
  • Commissioning and Quality Assurance/Control of equipment and software
  • Brachytherapy
  • Radiobiology in the clinic
  • Implementing patient-specific dosimetric QA
  • Radiation Protection and risk analysis
  • Induction of secondary tumours. 

Specific for clinicians:

  • Basic radiation physics
  • Dose calculation: principles and application in the TPS  
  • Radiotherapy equipment
  • Physicas of advanced radiotherapy.

Specific for physicists:

  • Reference and non-reference dosimetry
  • Modern dose calculation algorithms
  • QA for advanced delivery techniques
  • Oncologic concepts.

2. Clinical case discussions:

The participants are invited to prepare treatment plans for selected clinical cases (homework), based on case descriptions and CT scans as provided prior to the course. During the course, the plans are discussed regarding selected treatment techniques, planning solutions, constraints and objectives, choice of margins, protocols for image guidance, QA, etc, guided by a clinician and physicist teacher.


The participants are invited to prepare the homework for the clinical case discussions (above).

Teaching Methods

The course has a blended learning approach where recorded lectures, practical exercises (homework) and web-based interactive sessions and feedback are combined.


The course includes:

Kick-off – live web (10 min):

Introductory live web-meeting


Pre-recorded lectures -16 sessions of 45 minutes

Viewing of recorded lectures on key learning objectives.


Homework discussion sessions – live web (3 blocks of 120 minutes)

Interactive sessions – live web (9.5h)

In 14 sessions of 45 min the participants will meet with the faculty in interactive live web sessions. Each day will be finished with interactive 30 min Q&A block.


Extra material:

Methods of Assessment

  • Entry and exit exam
  • Evaluation form.
