Purpose Patient‐specific IMRT QA measurements are important components of processes
designed to identify discrepancies between calculated and delivered radiation doses …

Semiconductor dosimeters are ubiquitous in modern external-beam radiation therapy. They
possess key features. The response, electronically available in real time, is stable and linear …

The charges on this task group (TG) were as follows:(a) provide specific procedural
guidelines for performing the tests recommended in TG 142;(b) provide estimate of the …

Purpose To investigate the variability of the global gamma index (γ) analysis in various
commercial IMRT/VMAT QA systems and to assess the impact of measurement with low …

Purpose: In this study the effects of small systematic MLC misalignments and gravitational
errors on the quality of Rapidarc treatment plan delivery are investigated with respect to …

Purpose The SRS MapCHECK®, a recently developed patient‐specific quality assurance
(PSQA) tool for end‐to‐end testing of stereotactic radiosurgery (SRS) and stereotactic body …

The purposes of this study were to perform tests for the ArcCHECK QA system, and to
evaluate the suitability of this system for IMRT and VMAT verification. The device was tested …

Since the introduction of volumetric chemical dosimetry with Fricke gel dosimeters in the
1980s, three-dimensional (3D) dosimetry has been a promising technique for the clinic …

Purpose: The purpose of the present study was to investigate the ability of commercial
patient quality assurance (QA) systems to detect linear accelerator‐related errors. Methods …

The motivation for this study was to reduce physics workload relating to patient‐specific
quality assurance (QA). VMAT plan delivery accuracy was determined from analysis of pre …
