Liver irradiation
One of the things we are working on is the improvement of techniques to irradiate liver metastases. These tumors tend to move during treatment, which complicates things. They are not easy to spot on a CT scan either, which necessitates a marker in the tissue. Using a new irradiation device with a fully integrated MRI scanner (MR-linac), we no longer have to use a marker in the tissue. We can create a new radiation field right before every treatment session by making a scan to help adapt the treatment. We want to be able to create new scans during treatment and adapt the radiation field based on the movement we observe. By increasing our understanding of the precise location of the tumor, we can improve the aim of the radiation, which allows us to increase the dose without harming healthy tissue.
