4D treatment workshop on particle therapy

2 days of interactive and interesting lectures: from basic lectures about clinical implementation and the current status, over 4D dosimetry and imaging towards the discussion on online adaptive proton therapy and the potential and risks of high dose rates and advanced methods to minimize the motion. In addition, there will be an extended poster sessions with a poster award.

We’ve reached the maximum number of participants. If you would like to be put on the waiting list, please contact Astrid Moerman via a.moerman@hollandptc.nl.
