Detection and correction for EPID and gantry sag during arc delivery using cine EPID imaging
Medical Physics, 2012Electronic portal imaging devices (EPIDs) have been studied and used for pretreatment and in-vivo dosimetry applications for many years. The application of EPIDs for dosimetry in arc treatments requires accurate characterization of the mechanical sag of the EPID and gantry during rotation. Several studies have investigated the effects of gravity on the

EPID with Malicious Revocation
2021EPID systems are anonymous authentication protocols where a device can be revoked by including one of its signatures in a revocation list. Such protocols are today included in the ISO/IEC 20008-2 standard and are embedded in billions of chips, which make them a flagship of advanced cryptographic tools.

There has been an increasing interest in the application of electronic portal imaging devices (EPIDs) to dosimetric verification, particularly for intensity modulated radiotherapy. Although not water equivalent, the phantom scatter factor of an EPID, is generally assumed to be that of a full phantom, a slab phantom, or a mini phantom.

WE‐G‐BRB‐02: MU‐EPID an EPID Based Tool for IMRT Quality Assurance
Medical Physics, 2012Purpose: A software program (MU‐EPID) has been developed to perform patient specific IMRT pre‐treatment QA verification using an electronic portal imaging device. Methods: The software converts measured images of intensity modulated beams delivered to an EPID, into fluence maps that can be imported in the treatment planning system. The dose can then be

Electrophoretic image displays (EPIDs) are a very promising solution in the search for low-power, paper like reflective displays. While the technology is already mature, little is known about the internal physical properties. In this paper, we will describe which elements contribute to the charge transport and give an explanation of the steady state ...
