Medical Physics

As a leading radiotherapy department, we offer a wide variety of training and educational opportunities to those interested to improve their skills in the physics of radiotherapy.

Medical Physics Residency

The department of Radiation Oncology of the UMC Groningen is a certified training center for medical physics residents. Our four-year residency program in medical physics, with a specialization in radiotherapy physics, follows the program of the ‘Opleiding Klinische Fysica’ (‘OKF’). You will be trained and educated in basic medical physics skills, as well as specialized radiation therapy skills. The residency includes one-year for a scientific research project(s). For a broad perspective of the clinical practice of radiotherapy, you will spend nine months at the radiotherapy department of the Isala Klinieken in Zwolle.

The main objectives of our medical physics residency program are:

  • The right attitude
  • General scientific training
  • A broad knowledge of medical physics


A good written and oral understanding of the Dutch language is a mandatory requirement for entering our residency program.


We offer the possibility of a one-day exploratory visit to our department for job orientation. Please contact our secretary’s office at +31-50 361 3674.

For information regarding our residency program and enrollment opportunities, please contact our residency program coordinator Aart van 't Veld, PhD.

Our research program

Our department has an extensive research and development program aimed at the continuous improvement of the quality of radiotherapy treatments. As such, we offer opportunities towards earning a doctorate degree (PhD), which will be obtained at the Faculty of Medical Sciences of the University of Groningen.

At the moment we have PhD students researching:

  • Personalized adaptive radiotherapy in head and neck cancer patients
  • Robustness evaluation of scanned proton therapy for lung patients - taking into account setup and range uncertainties in combination with effects due to respiratory motion
  • Image biomarkers
  • A “plan of the day approach” for proton therapy – investigating a variety of strategies for adaptive therapy of moving targets with scanned proton beams
  • Reducing radiotherapy side effects in head and neck cancer patients using a Comprehensive Individual TOxicity Risk profile: The CITOR project


The coordinator of the PhD research program is Prof. Stefan Both. PhD students are supervised by (medical) physicists from our department. 

For information about and opportunities within our PhD research program, please contact Prof. Stefan Both or our secretary’s office at +31-50 361 3674.

Master track Biomedical Engineering (≈ 9 weeks)

Our department is actively involved in the Diagnostic Imaging & Instrumentation track of the master’s degree in Biomedical Engineering (BME). We teach the course Medical Physics for Radiation Oncology (5EC). The course consists of weekly meetings over a period of nine weeks, focusing on both theoretical and practical aspects of the physics of radiotherapy. From treatment preparation (treatment planning) to treatment delivery using a (particle) accelerator, including the methods applied for treatment verification and quality assurance.

Some examples of the practical aspects taught within our radiotherapy department are:

  • Measurements at a linear accelerator using a variety of detectors and phantoms
  • Investigating the properties of megavoltage photon beams in a waterphantom
  • Treatment position verification and (corresponding) safety margins
  • A simple calculation formalism for the delivered dose of a linac
  • Complex 3D dose calculations in a patient geometry


A master's degree in Biomedical Engineering with the above specialization, in combination with a bachelor’s degree in either Physics or Life Science & Technology, allows students to apply for the postgraduate Medical Physics residency program.

For more information about our course in Medical Physics for Radiation Oncology, please contact the course coordinator Heidi Lotz, PhD or our secretary’s office at +31-50 361 3674.

Final year project and internships (3 – 12 months)

We offer master’s students in Biomedical Engineering and in Technical Medicine the opportunity to conduct their final year project (approximately 40 EC) at our department. These projects tie in with our ongoing departmental research program and its priority research themes. We also the possibility for a 3 to 6 months internship (10-20 EC). 

Please contact Marianna Sijtsema, PhD or our secretary’s office (+31-50 361 3674).

We offer opportunities for post-doctoral research that complements our own research program. We furthermore provide opportunities towards gaining clinical experience. For information regarding internships, please see the tab labeled ‘Students’.

Please contact Prof. Stefan Both or our secretary’s office (+31-50 361 3674) for more information.
