Author: Marlies Pasler, Lake Constance Radiation Oncology Center, Friedrichshafen (Germany) Summary: Evaluation of the potential of the IQM System to catch errors before they become clinically relevant. They also checked if IQM would help them to improve the efficiency of their processes and finally they checked if IQM would replace their current pre-treatment QA. They

Author: Livia Marrazzo, et al, University of Florence, AOU Careggi Florence (Italy) Summary: Evaluate the correlation between the changes in the detector output signal induced by small delivery errors with other metrics, such as the γ passing rate and the DVH variations. The authors concluded that IQM is capable of detecting small delivery errors and

Author: Gloria Miori, et al, Azienda Provinciale per i Servizi Sanitari, Trento (Italy) Summary: 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

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
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.

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)

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.
