Development of a new type of leaf and drive concept for multi-leaf collimators (MLCs) with lower weight and reduced complexity, as well as superior positioning speed and precision by realizing a dynamic real-time controlled leaves of an MLC to compensate for organ movements and achieve more precise tumor irradiation. The novel system architecture with real-time requirements allows reduction of control components in the radioactive environment of the radiation source to ensure higher reliability and allows dynamic real-time control of the leaves of an MLC to compensate for organ movements and achieve more precise tumor irradiation, which would optimally support the requirements of image-guided radiotherapy, such as e.g. MR-Linac systems.

This project was a joint project between the DKFZ and the Fraunhofer Institute PAMB in Mannheim and built an exemplary prototype as a proof-of-concept. Our working group assumed the role of project coordinator and implemented the project according to the project plan.
