Effect of the IQM on 4-, 6-, 10-MV and 6FFF photon beams
Trang Hong Thi Nguyen, et al, Kanazawa University (Japan)
Assessment of surface dose, PDD20,10 , TPR20,10 , PDD curves, inline and crossline profiles, transmission factor, and output factor with and without the IQM detector in order to investigate the effect of the IQM detector on 4, 6, 10, and 6-MV flattening filter-free (FFF) photon beams.
A new wedge-shaped ion chamber component for BEAMnrc to model the IQM System
Oluwaseyi Michael Oderinde, et al, University of the Free State, Bloemfontein (South Africa)
Development of a new component module (CM) to accurately model the IQM to be used in the BEAMnrc Monte Carlo (MC) code
Influence of the IQM on high energy photon beam: A multi-centre study
Bozidar Casar, et al, Multi-centre study of 9 RT departments
This article discusses the influence of the Integral Quality Monitor (IQM) transmission detector on photon beam properties. The authors evaluated the change of beam quality (beam hardening), surface dose and the beam attenuation of the IQM detector.
Verifying TBI with IQM
Gabriele Guidi, et al, University Hospital of Modena (Italy)
Evaluation of IQM for the verification of TBI treatments. They investigated the influence of the IQM Detector on depth dose curves and beam profiles for an extended SSD of 170cm. The presentation outlines the considerations that should be applied when utilizing IQM for TBI verification. They concluded that IQM can be used for TBI verification.
Integrating IQM into a commercial planning system
Bruce Perrin, et al, Christie Hospital, Manchester (UK)
Investigation of the potential challenges when integrating IQM into a commercial planning system. They compared data measured in a waterphantom with and without the IQM detector for various energies (6,10 & 6FFF). They evaluated the IQM data against clinical models in Pinnacle 9.8 and analyzed the magnitude of adjustments assessed. They finally verified their results by delivering various treatment plans to the Delta 4 through IQM.
Evaluation of IQM for monitoring real-time delivery
Gloria Miori, et al, Azienda Provinciale per i Servizi Sanitari, Trento (Italy)
Evaluation of the IQM System for real-time beam delivery verification. They analysed the IQM beam attenuation and IQM’s ability to detect VMAT delivery errors. They concluded that the IQM beam attenuation can be considered to be homogenous in both X and Y directions and the machine-specific beam attenuation percentage could be used to rescale treatment plan dose for clinically IQM use. IQM shows appreciable features in detecting real-time errors and for time-saving QAs
Characterization and evaluation of the IQM System
David Hoffman, UC Comprehensive Cancer Center, Sacramento (USA)
