Adaptive‐driven CT simulation‐free multi‐fraction SBRT radiotherapy: Initial clinical experience

Journal of Applied Clinical Medical Physics, Volume 26, Issue 8, August 2025.
Abstract Introduction Using diagnostic CT for radiotherapy (RT) planning can bypass traditional CT simulation but introduces challenges in patient positioning and Hounsfield unit (HU) fidelity, affecting dose accuracy. Here a Varian Ethos adaptive‐driven CT direct‐to‐treatment (DtT) multi‐fraction stereotactic body radiation therapy (SBRT) workflow is ...

Bringing Small Devices, Giving Design Advice: Introducing Radiation Protection Practices in Greece via the IAEA's Visiting Professor Program**

Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 91-111, August 2025.
Abstract This paper examines how an International Atomic Energy Agency (IAEA) expert mission for technical assistance in the late 1950s to Greece was effectively transformed into a mission to achieve the IAEA′s central objective: to consolidate its position as the leading global authority on radiation protection. The study focuses on the work of Alfred
