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.

Performance optimization of the Varian aS500 EPID system
Journal of Applied Clinical Medical Physics, 2006 Today, electronic portal imaging devices (EPIDs) are widely used as a replacement to portal films for patient position verification, but the image quality is not always optimal. The general aim of this study was to optimize the acquisition parameters of an amorphous silicon EPID commercially available for clinical use in radiation therapy with the view
