EPID in vivo dosimetry in RapidArc technique [PDF]
The aim of the study was to estimate the dose at the reference point applying an aSi-EPID device in the course of patient treatment.The method assumes direct proportionality between EPID signal and dose delivered to the patient reference point during the treatment session.

EPID – a useful interfraction QC tool [PDF]
Abstract Biomedical accelerators used in radiotherapy are equipped with detector arrays which are commonly used to obtain the image of patient position during the treatment session. These devices use both kilovolt and megavolt x-ray beams.

EPID with Efficient Proof of Non-Revocation
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.
