EPID‐based dosimetry to verify IMRT planar dose distribution for the aS1200 EPID and FFF beams [PDF]
Journal of Applied Clinical Medical Physics, 2016 We proposed to perform a basic dosimetry commissioning on a new imager system, the Varian aS1200 electronic portal imaging device (EPID) and TrueBeam 2.0 linear accelerator for flattened (FF) and flattening filter‐free (FFF) beams, then to develop an image‐based quality assurance (QA) model for verification of the system delivery accuracy for intensity‐

EPID with Efficient Proof of Non-Revocation
Proceedings of the 2022 ACM on Asia Conference on Computer and Communications Security, 2022 EPID systems are anonymous authentication mechanisms which are standardized by ISO/IEC and massively deployed in Intel processors. They are related to the large family of privacy-preserving signatures but differ in that they provide a very pragmatic way of revoking members.

Dose calibration of EPIDs for segmented IMRT dosimetry [PDF]
Journal of Applied Clinical Medical Physics, 2014 The purpose of this study was to investigate the dose response of amorphous silicon (a‐Si) electronic portal imaging devices (EPIDs) under different acquisition settings for both open jaw defined fields and segmented intensity‐modulated radiation therapy (IMRT) fields. Four different EPIDs were used.
