Conclusions: An algorithm to reconstruct delivered patient 3D doses from EPID exit dosimetry measurements was presented. The method was applied to phantom and patient data sets, as well as for dynamic IMRT and VMAT delivery techniques. Results indicate that the EPID dose reconstruction algorithm presented in this work is suitable for clinical implementation.]]> Sat 24 Mar 2018 07:40:16 AEDT ]]> First experience with real-time EPID-based delivery verification during IMRT and VMAT sessions https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26356 Sat 24 Mar 2018 07:35:52 AEDT ]]>
