„An intriguing device...“
John Wong, Ph.D. Head of Radiation Oncology Physics, Johns Hopkins University, Baltimore, USA
„This allows everyone to stay ahead of the game of QA.“
Stanley Benedict, Ph.D.Professor & Vice Chair of Clinical Physics, Department of Radiation Oncology, University of California at Davis Comprehensive Cancer Center, USA
"The best idea I have seen in years..."
Uwe GötzMedical Physicist, St. Vincenz Krankenhaus, Limburg, Germany
"IQM constitutes a paradigm shift in treatment verification..."
David Jaffray, Ph.D.Head of Radiation Physics Department, Princess Margaret Cancer Centre, Toronto, Canada
"A physics tool for the independent verification of the final beam product."
Robert Heaton, Ph.D.Medical Physicist, University of Toronto, Canada
"Measuring with IQM is a piece of cake..."
Lan Lin Ph.D.Medical Physicist, Johns Hopkins Group, Washington, D.C., USA
"I see endless possibilities..."
Henk Huizenga, Ph.D. Head of Radiation Oncology Physics (retired), Radboud University Nijmegen, The Netherlands
"The IQM System is a highly sensitive dose monitoring device.”
Stefania Pallotta, Ph.D.Department of Experimental and Clinical Biomedical Sciences “Mario Serio”, University of Florence, Florence, Italy
"IQM is an especially good candidate for monitoring small fields due to its unique detector design."
David Hoffman, Ph.D.Medical Physicist, University of California San Diego, USA
"Our study demonstrates clinically negligible changes in 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 MarrazzoMedical 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 WirtzLake 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
