Testing IQM
Author:
Cinzia Talamonti, et al, University of Florence, AOU Careggi, Florence (Italy)
Summary:
The authors evaluated the IQM during the pre-clinical testing. She concludes that IQM provides optimal performance for signal reproducibility of complex IMRT plans. IQM is capable of detecting small errors in MU and leaf positions sufficient for clinical practice
Reproducibility and sensitivity of IQM
Author:
Chiara Arilli, et al, University of Florence, AOU Careggi, Florence (Italy)
Summary:
The authors evaluated the output signal reproducibility and sensitivity in detecting small errors in delivery parameters of IMRT step and shoot treatments using the IQM System as well as the correlation between IQM signal variations and 3Dγ, 2Dγ and DVH parameters.

Characterization and evaluation of the IQM System
Author:
David Hoffman, UC Comprehensive Cancer Center, Sacramento (USA)
Summary:
This article outlines a comprehensive evaluation of the Integral Quality Monitor (IQM) that took place at the UC Davis Comprehensive Cancer Center throughout the year 2015.
Real-time detection of deviations
Author:
Martijn Kusters, Richard Canters, Radboud UMC, Nijmegen (The Netherlands)
Summary:
The IQM enables a clinic to do real-time, intra-fraction monitoring of beam delivery. The error sensitivity and specificity can be expected to be sufficient for clinical practice, and performs at least as well as their current equipment (Scandidos Delta 4)
Performance study of IQM for SBRT treatments
Author:
Makan Farrokhkish, Princess Margaret Cancer Centre, Toronto (Canada)
Summary:
IQM is well suited to verify state-of-the-art SBRT treatments utilizing FFF Rapid Arc treatments on a Varian TrueBeam linear accelerator
In vivo dosimetry of stereotactic radiation therapy
Author:
Jianguo Qian, et al, Johns Hopkins University, Baltimore (USA)
Summary:
The author draws the preliminary conclusion that IQM is a stable dosimetric system and can detect dosimetric deviations caused by small leaf errors in stereotactic radiation therapy. The sensitivity to leaf errors is more pronounced for relatively small fields (i.e., small targets) in SBRT. IQM appears to be more sensitive than Mapcheck2 to small leaf errors in small SBRT targets while showing similar sensitivity in relatively large SBRT targets.
In vivo dosimetry of conventional and rotational IMRT
Author:
Lan Lin, et al, Johns Hopkins University, Baltimore (USA)
Summary:
Evaluation of the accuracy, sensitivity (picket-fence test) and constancy of the IQM for conventional intensity modulated radiation therapy (IMRT) and rotational volumetric modulated arc therapy (VMAT).
Sensitivity Analysis of the IQM System using Monte Carlo Simulation
Author:
Oluwaseyi M. Oderinde, et al, University of the Free State, Bloemfontein (South Africa)
Summary:
Evaluation of the IQM error sensitivity in beam segments using EGSnrc/BEAMnrc Monte Carlo (MC) codes
Response characteristics of the 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.
Efficient and enhanced QA testing of Linear Accelerators using IQM
Author:
Andrew Jongho Jung, Princess Margaret Cancer Centre, Toronto (Canada)
Summary:
Investigating the use of IQM for various Machine QA applications: beam output, beam symmetry, relative dose factor, MLC calibration, output as function of dose rate, dose linearity and output as function of gantry angles
Initial evaluation of the IQM
Author:
Bruce Perrin, et al, Christie Hospital, Manchester (UK)
Summary:
The authors validated the effectiveness and reliability of the IQM to monitor the correct delivery of daily fractions.
