  • Real-time beam monitoring for error detection in IMRT plans and impact on dose-volume histograms

    This multi-center study by Livia Marazzo, published in the German Journal of Radiation Therapy and Oncology tests the sensitivity of the Integral Quality Monitor (IQM) transmission detector for online dose monitoring of IMRT treatment techniques to detect small delivery errors. The article furthermore investigated the correlation between changes in the IQM signal, induced by small delivery errors, with other metrics like Gamma passing rate and dose-volume histogram metrics.  Download this article to learn about the high sensitivity of the IQM transmission detector for small delivery errors as well as the good correlation between the IQM detector signal and DVH metrics.

  • Influence of the Integral Quality Monitor transmission detector on high energy photon beams: A multi-centre study

    This article discusses the influence of the Integral Quality Monitor (IQM) transmission detector on photon beam properties. The authors evaluated data acquired at nine different Radiation Therapy centers and concluded that the magnitudes of changes observed justify treating IQM either as energy-specific tray factors in the treatment planning system or alternatively as a set of modified output factors for each linac energy. Download this article for some valuable guidance for implementing the IQM System into your clinical routine.

  • Beam Delivery Check and In-Vivo Dosimetry during Breast Radiotherapy Treatment

    Cinzia Talamonti and her colleagues from the University of Florence, Italy verified the delivery of the prescribed dose during radiotherapy treatment using the IQM in combination with portal imaging, together with the software SoftDiso (Best Medical Italy Srl) for in-vivo measurements. They evaluated the ability of detecting positional and delivery errors intentionally introduced during breast treatments. Download the full poster that was shown during the AIFM Conference in Perugia, Italy in February 2016.

  • Preliminary tests with the IQM system - the University of Florence experience

    Stefania Pallotta states that IQM provides an optimal performance for IMRT QA, based on the results of this study, which saw intra-fractional standard deviation (%STD) of 0.04% and inter-fractional %STD of up to 0.36% for complex IMRT cases over a period of multiple weeks.

  • Testing IQM: A system for real-time monitoring of complex radiotherapy treatments

    Stefania Pallotta from University of Florence, Italy evaluated the IQM during pre-clinical testing. She concludes that IQM provides optimal performance for signal reproducibility for complex IMRT plans. Her work demonstrated that IQM is capable of detecting small errors in MU and leaf positions and is sufficient for clinical practice. Download the complete poster that was shown at the IEEE conference in Milano, Italy

  • Delivery errors detectability with IQM, a system for real-time monitoring of radiotherapy treatments

    Livia Marrazzo and her colleagues at the AOU Careggi in Florence evaluated the correlation between changes in the detector output signal induced by small delivery errors with other metrics, such as the Gamma pass rate and DVH variations. They concluded that IQM is capable of detecting small delivery errors and that it exhibits a good correlation with other metrics currently used to determine the quality of a treatment plan.
