This study used four QA devices (Scandidos Delta4, PTW 2D‐array, iRT systems IQM, and PTW Farmer chamber). Nine retrospective VMAT plans were used and nine MLC error plans were generated for all nine original VMAT plans. Download this article to learn about the unrivaled error sensitivity of the IQM transmission detector for systematic MLC errors, especially for small aperture sizes, such as for lung SBRT.

"Why didn't anybody think of this before?"
A sentence that we hear during almost every presentation.
"Our study demonstrates clinically negligible changesin beam quality and surface dose for all investigated beams.”
Bozidar Casar, Ph.D., Medical Physicist, Institute of Oncology Ljubljana, Slovenia
"The results of our study demonstrate the clear and consistent correlation of the IQM signal with DVH metrics.”
Livia Marrazzo, Medical Physic Unit, Careggi University Hospital, Florence, Italy
"IQM is a key component of our automated treatment quality control and allows us to fully comply with the requirements defined in the 2013/59/EURATOM directive."
Holger Wirtz, Lake Constance Radiation Oncology Center, Singen-Friedrichshafen, Germany
"The quick setup and fully automated handling of all clinical data significantly reduces the time we need for Plan QA. Our clinical evaluation has shown that the error detection capability of the IQM System is at least as good, and in many cases even better, than with conventional 3D phantoms."
Otto Sauer, Ph.D., Head of Medical Physics, University of Würzburg, Würzburg, Germany
