4D Quality Assurance

Dose reconstruction based on machine log-files and motion monitoring for 4D adaptive treatment approaches

Motion induced uncertainties hamper the clinical implementation of pencil beam scanning proton therapy (PBS-PT). We work on a methodology for fraction-wise retrospective 4D dose reconstruction, aimed at the evaluation of treatment quality during treatment.
