About: The Experimental Clinical Physics group is developing, exploring and clinically evaluating new workflows for the hybrid 1.5T MRI linac. This system has been developed in UMC Utrecht and is currently on the market via Elekta as the Unity system. At UMC Utrecht two clinical Unity systems are operational, the third one will follow later in 2021, whereas the original prototype system is still present as a museum piece. The group is working to live up to the promise of the MRILinac, that is, mitigate the impact of anatomical motion on the radiotherapy treatment for higher precision radiation delivery. To achieve this, expansion of functionality of the MRILinac is addressed to enable for instance gating and/or tracking of the radiation beam, on-the-fly re-planning and arc therapy. New real-time machine interaction is explored but also a rapid prototype environment is built up to develop and evaluate new workflows.
