Automated planning architectures for online adaptive radiotherapy: A narrative review of the Ethos and Unity/Monaco platforms

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Online adaptive radiotherapy (OART) modifies treatment plans using anatomy‐of‐the‐day imaging, but successful clinical implementation depends on automated planning strategies that can generate high‐quality plans within the constraints of an online workflow. This narrative review compares the automated planning architectures of the Varian Ethos
