UFS - External Beam patient dose verification

External beams patient dose verification based on the IQM output signals

Author:
Courage Mahuvava, et al, University of the Free State, Bloemfontein (South Africa)

Summary:
The purpose of this study was to make use of IQM field output signals to calculate the MUs delivered through an arbitrary treatment field in order to convert Monte Carlo-generated dose distributions in a patient model into absolute dose.

Plan QA with IQM (German)

Author:
Sonja Wegener, et al, Unversity Clinic Wurzburg (Germany)

Summary:
Clinical experience using IQM for VMAT Plan QA.

White Paper: Matching with IQM – The GenesisCare experience

Author:
Kilian Michel, et al, iRT Systems, Koblenz (Germany)

Summary:
Four (4) Elekta Versa HD Linear accelerators at different sites within a network of 16 cancer centers were matched for the 6MV beam energy. As part of commissioning IQM detectors at each of the 16 sites we investigated the agreement of IQM and waterphantom measurements among the four matched machines and implemented a universal beam model to calculate predicted IQM measurements for them.

UFS - A new wedge-shaped

A new wedge-shaped ion chamber component for BEAMnrc to model the IQM System

Author:
Oluwaseyi Michael Oderinde, et al, University of the Free State, Bloemfontein (South Africa)

Summary:
Development of a new component module (CM) to accurately model the IQM to be used in the BEAMnrc Monte Carlo (MC) code

Integrating IQM into a commercial planning system

Author:
Bruce Perrin, et al, Christie Hospital, Manchester (UK)

Summary:
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.

Author:
Makan Farrokhkish, Princess Margaret Cancer Centre, Toronto (Canada)

Summary:
Evaluation of the intrinsic and effective spatial sensitivity, response as a function of field size, beam energy and dose rates

Online quality assurance of external beam radiation therapy

Author:
David Hoffman, UC Comprehensive Cancer Center, Sacramento (USA)

Summary:
Evaluation of the stability and accuracy of each IQM system feature.

White Paper: IQM Detector characteristics: Signal linearity and dose rate dependence

Author:
iRT Systems, Koblenz (Germany)

Summary:
Investigation of  the signal linearity and dose rate dependence of IQM System

PMH - An IQM

An IQM System for real-time verification of IMRT

Author:
Mohammad Islam, et al, Princess Margaret Cancer Centre, Toronto (Canada)

Summary:
The proof of concept publication (2009) for the IQM system
