Real-time beam monitoring for error detection in IMRT plans and impact on DVH
Author: Livia Marrazzo, et al, Multi-centre study of 3 RT departments Summary: This article shows the ability of detecting small delivery errors with a transmission detector for online monitoring of Intensity Modulated Radiation Therapy (IMRT) treatments. The authors also show how the IQM signal deviations strongly correlate with changes in the dose-volume-histogram for the PTV
