Part 2 of the study found when these margins were used in an Ethos OART workflow, they resulted in CTV coverage that was superior to an IGRT workflow with 7-mm margins. Conclusions: A 4mm prostate margin and 5-mm seminal vesicles margin in an OART workflow with verification maging are adequate to ensure coverage on the Varian Ethos system. Larger margins may be required if using an OART workflow without verification imaging.]]> Wed 26 Jun 2024 16:18:04 AEST ]]> Assessment of semi-automated stereotactic treatment planning for online adaptive radiotherapy in ethos https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51445 Tue 05 Sep 2023 17:55:17 AEST ]]> Varian ethos online adaptive radiotherapy for prostate cancer: Early results of contouring accuracy, treatment plan quality, and treatment time https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45741 Fri 04 Nov 2022 10:13:02 AEDT ]]>
