Over the past 20 years, research and development in medical physics has improved the accuracy and conformity of radiotherapy tremendously. This includes the development of intensity-modulated radiotherapy (IMRT), which allows the delivery of highly conformal dose distributions to complex shaped tumors. More recently, the development of image guided adaptive radiotherapy has provided means to correct for geometric changes and organ motion over the course of therapy. The medical physics group contributes to these technological advances of radiotherapy through both clinically applied and fundamental research projects.
We focus on 3 areas of research:
- Radiotherapy treatment planning: We conduct research on mathematical optimization methods for radiotherapy planning to further improve treatment planning systems. This includes both X-ray therapy as well as proton therapy.
- Target delineation and outcome prediction: Here, we focus on quantitative analysis of medical images such as MRI, CT and PET, with the goal of precisely defining the region to be irradiated and predicting the patient's response to treatment. Work in this domain is integrated into the UZH Clinical Research Priority Program Artificial intelligence in oncological imaging.
- Adaptive radiotherapy: We further develop state-of-the-art systems to correct for motion of the tumor. Our department is the first in Switzerland to install a MRI-Linac, a combination of MRI scanner and radiotherapy device. In addition, we work on methods to compensate for tumor motion using counter-motion of the treatment table.
Related to our work on Target Volume Definition and Radiomics, we will organize a symposium on "Augmented intelligence for quality improvement in Oncology". On January 30, 2020, speakers from both academia and industry will present their perspective on the role of AI in oncological imaging and therapy. Registration is open!

Related to our research on target volume definition, we will organize a workshop on 'Computational methods for clinical target volume definition' as part of the 3rd ESTRO physics workshop in Budapest (October 25/26, 2019).
Save the date: Between Aug 30 to Sep 01, we will be presenting research on MR-guided radiotherapy as well as Artificial Intelligence in Medicine at the Scientifica.
On July 11, 2019 we will celebrate the startup of our MR-Linac device, the first hybrid device combining a MRI scanner with a radiotherapy accelerator installed in Switzerland.
