Radiation Physics

Section edited by Christoph Bert and Katia Parodi

The Radiation Physics section aims at providing a platform for medical physics research and applications in radiation oncology. This includes innovative developments in the application of physical sciences to radiation oncology, spanning the broad range of advanced beam delivery and imaging, dosimetry, computation, modeling and data processing. Contributions proposing innovative methodological approaches or presenting original assessment on the clinical relevance of new technologies are welcome. Space is also given to review contributions on timely topics, as well as invited key reviews from renowned experts. Hence, the Radiation Physics section addresses contemporary cutting-edge research and methodological advancements for improved clinical practice, as well as reviews of relevant medical physics issues in radiation oncology, offering a fast review process and broad outreach.
