EPIDs and QA of advanced treatments
Journal of Physics: Conference Series, 2019 Abstract In this paper I will summarize the various possibilities of EPIDs for their use as tools for QA of advanced treatments. After elucidating the choice of EPIDs for this purpose, I will review the use of EPIDs for pre-treatment and in vivo (transit) dosimetry applications.
