Purpose: Electronic Portal Imaging Devices (EPIDs) have been widely utilized for Patient-
Specific QA (PSQA) and their use for transit dosimetry applications is emerging. Yet there …

Purpose To investigate the effectiveness of an EPID-based 3D transit dosimetry system in
detecting deliberately introduced errors during VMAT delivery. Methods An Alderson …

Background Artificial intelligence (AI)‐based gamma passing rate (GPR) prediction has
been proposed as a time‐efficient virtual patient‐specific QA method for the delivery of …

Purpose Despite their availability and simplicity of use, Electronic Portal Imaging Devices
(EPID s) have not yet replaced detector arrays for patient specific QA in 3D. The purpose of …

Purpose The aim of this paper is to characterize two different EPID-based solutions for pre-
treatment VMAT quality assurance, the 2D portal dosimetry and the 3D projection technique …

Purpose In vivo EPID dosimetry is meant to trigger on relevant differences between
delivered and planned dose distributions and should therefore be sensitive to changes in …

Purpose To assess the sensitivity of various EPID dosimetry alert indicators to patient‐
related variations and to determine alert threshold values that ensure excellent error …

With new radiotherapy techniques, treatment delivery is becoming more complex and
accordingly, these treatment techniques require dosimetry audits to test advanced aspects of …

Intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT)
are relatively complex treatment delivery techniques and require quality assurance (QA) …
