In addition to the treatment of patients in clinical studies, MedAustron’s accelerator facility offers an exciting and wide range of research opportunities.

On the one hand, translational research addresses topics close to medical applications, on the other hand, particle beams can also generally be used in radiation physics and applied particle physics. Medical University of Vienna and Vienna University of Technology are the priority partner institutes for our research projects, whose implementation is decided by an independent advisory board. There is also close cooperation in scientific work with the Institute for High Energy Physics of the Austrian Academy of Sciences, University of Applied Sciences Wiener Neustadt and Medical University of Graz. An executive committee supports practical research work on site and accompanies research progress. Thomas Schreiner and Dietmar Georg are responsible for the coordination of these research activities.


Research fields

Six research projects have been defined for the research period from 2019 to 2021, in addition to the required commissioning of carbon ions and 800 MeV protons.

Intrafractional adaptive radiotherapy

The treatment of moving target volumes with scanned particle beams has long been an important area of research in ion beam therapy. For intrafractional adaptive radiotherapy, i.e. in case of changes during an irradiation fraction, the focus is in the field of medical image processing, four-dimensional dosimetry and special methods in radiation planning.

Interfractional adaptive radiotherapy

Interfractional adaptive radiotherapy also deals with position changes of the target volumes, where the time interval of the movement is larger, i.e. changes between the individual radiation days (fractions). Treatment adaptations are based on magnetic resonance images, which provide information on morphological changes and changes in tumour characteristics. So-called deep learning approaches are also used for evaluating and further processing the individual images.

Magnetic resonance-based particle therapy

Research in the field of magnetic resonance-based beam application or development of combining magnetic resonance imaging and ion beam therapy is an emerging topic in radiotherapy. In contrast to photon therapy, the particle beam is directly influenced by the magnetic field in ion beam therapy. Studies on the effects on dose distribution, on dosimetric measurements and finally on patient treatment are the starting point for magnetic resonance-based particle therapy.

Imaging with ion beams

MedAustron offers the possibility to investigate proton computed tomography with energies of up to 800 MeV. Such high proton energies are not used in therapy. In order to reduce distance uncertainties in the irradiation planning process, it is of essential interest to improve determining the energy output of the particles.

Energy transfer mechanisms

Currently, treatment planning in ion beam therapy is based on the product of absorbed dose in water with a biological weighting factor. However, this approach is not sufficient for a comprehensive quantitative description of biological impacts. Therefore, microdosimetric spectra are recorded by means of experimental measurements, which represent the cornerstone for further correlation with biological data.

Preclinical research

Preclinical research focuses on the investigation of molecular biological and immunological processes in the tumour and its microenvironment, which contributes significantly to the therapy resistance of the tumour. The effects of ion beam therapy on the tumour microenvironment are currently unknown and are being explored in adequate spheroid and xenograft models. In addition, it is planned to visualize and investigate radiation-induced processes in the tumour using non-invasive preclinical imaging techniques.


Topics for academic theses

Due to the close cooperation of MedAustron with Austrian universities and universities of applied sciences, there is the unique possibility for students to do their final theses (MSc or BSc) at the MedAustron particle accelerator. Currently, student theses are possible in the following areas:

For the implementation of research projects, scientists can use both proton and carbon ion beam to a defined extent as well as dedicated premises.

The beam parameters essentially comprise those that are also intended for medical use. The only exception is the maximum proton energy, which can be increased up to 800 MeV.

A separate irradiation room, which is not used for patients, has the following properties:

  • room size of about 96 m² with the possibility of two radiation stations one behind the other
  • robotic positioning and verification system (ring imaging system), which is identical to the that used in the clinical irradiation rooms
  • removeable nozzle, research magnet with a maximum magnetic field of 1 T, external cooling facilities, cooling-down room and local control room

According to the main research areas in radiation biology, radiation physics and applied particle physics, scientists can also use differently equipped laboratories, for example:

  • cell culture laboratory with incubators and laminar flow workstations
  • chemistry laboratory with digester, staining devices and safety cabinets workbenches, microscopes
  • X-ray reference source, VME electronics and much more.
  • dosimetry laboratory with different dosimetric systems and phantoms
  • software laboratory with several irradiation planning systems and Monte Carlo applications

The research infrastructure at MedAustron also includes preparation and storage rooms as well as office workstations and a meeting room.
