This report provides guidance for the implementation of online treatment monitoring (OTM)
solutions in radiotherapy (RT), with a focus on modulated treatments. Support is provided …

BACKGROUND AND PURPOSE: To demonstrate the feasibility of back-projection portal
dosimetry for accurate 3D dosimetric verification of volumetric-modulated arc therapy …

Purpose: Radiation treatments are trending toward delivering higher doses per fraction
under stereotactic radiosurgery and hypofractionated treatment regimens. There is a need …

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 …

The objective of this paper is to provide a comprehensive review of the advancements and
techniques in real time two-dimensional (2D) dosimetry for external radiation therapy with …

Purpose: A patient‐specific quality assurance (QA) method was developed to verify gantry‐
specific individual multileaf collimator (MLC) apertures (control points) in volumetric …

We validate the dosimetric performance of COMPASS®, a novel 3D quality assurance
system for verification of volumetric-modulated arc therapy (VMAT) treatment plans that can …

The dosimetric consequences of errors in patient setup or beam delivery and anatomical
changes are not readily known. A new product, Per FRACTION (Sun Nuclear Corporation) …

Purpose The aim of this study is to investigate the performance and limitations of a real-time
transit electronic portal imaging device (EPID) dosimetry system for error detection during …

Although much literature has been devoted to portal dosimetry with the Varian amorphous
silicon (aSi) portal imager, the majority of the described methods are not routinely adopted …
