Dosimetric Validation of Ethos Online Adaptive Radiotherapy for Prostate Cancer: An End-to-End Phantom Study

Background/objectives

Online adaptive radiotherapy (oART) re-optimizes treatment on the anatomy of the day, but automatically generated plans require dosimetric verification and dose-volume assessment. We performed an end-to-end validation of the Varian Ethos workflow for prostate cancer, including cross-adaptation between two phantom anatomies.
