Combined use of IQM and an EPID-Based In Vivo Dose Monitoring System

Author: Cinzia Talamonti, et al, University of Florence (Italy) Summary: Evaluation of the combined use of the IQM system and SoftDiso portal dosimetry software, for in vivo dose monitoring by simultaneous detection of delivery and patient setup errors in whole breast irradiation. The combined use of the IQM and SoftDiso allows for fast identification of […]

Evaluation of the signal response with the EPID and the IQM for SBRT QA

Juergen Oellig

Author: Adam Harpley, et al, Vanderbilt University Medical Center, Nashville (USA) Summary: The clinical physics group introduced a variety of clinically significant treatment delivery errors into 8 retrospective SBRT plans and compared the error sensitivity of IQM to their Varian Portal Dosimetry system.

Evaluation of the IQM for 4MV x-ray beam

Juergen Oellig

Author: Haruna Yokoyama, et al, Kanazawa University (Japan) Summary: The clinical physics group introduced a variety of clinically significant treatment delivery errors into 6 different treatment techniques (3x 3DCRT, 1x IMRT and 2x VMAT) all utilizing 4MV treatment beams. They concluded that IQM was more sensitive to the MLC errors than the conventional QA method.

Optimization of DLG and MLC transmission factors

Juergen Oellig

Author: Stephen Martinez, et al, Vanderbilt University Medical Center, Nashville (USA) Summary: The clinical physics group aimed to compare the capability of the iQM system for optimizing MLC model specific parameters: Dynamic Leaf Gap and Transmission Factor to a IBA MatriXX spatial array. IQM shows a VERY small variation in the measured results and is

Sensitivity of the IQM to errors of VMAT plans

Juergen Oellig

Author: Gary Razinskas, et al, Unversity Clinic Wurzburg (Germany) Summary: This article verifies the accuracy of the signal prediction for the Synergy Agility MLC. Tolerance criteria for VMAT plan verification with the IQM were obtained from the observed sensitivity for the detection of incorrectly delivered plans. This study used 60 VMAT plans to compare the
