Research
Our research activities are in the field of imaging guided radiotherapy of cancer. Imaging techniques such as PET and MR have great potential to identify cancer patients with tumor recurrence or persistence. PET and MR may also help to improve the radiotherapy treatment, for example through a more precise delineation of tumor versus normal tissue which can improve the planning of the radiation dose. Another example is that parameters can be derived from the images and be used to characterize the tumor in terms of its biology. This can help to determine radioresistant subregions in the tumor, which may be prognsotic for the response to therapy and serve as a target for a higher radiation dose. Such patient indivudal, imaging based treatment adaptation may in future help to achieve a better treatment outcome. Our research therefore addresses different aspects of integrating PET/MR imaging into radiotherapy:
- Radiotherapy tailored imaging solutions for combined PET/MRI
- New strategies to characterize tumors in terms of biology and radiation therapy resistance using multiparametric PET/MRI, machine learning methods and radiomics
- Tumor control probability modelling and radiotherapy dose painting based on functional image data
- Machine learning of functional image data for automatic tumor delineation
- Optimization of radiotherapy specific imaging protocols for PET/MRI
- Streamlining synthetic CT generation and PET attenuation correction
