SESSION – How to make your presentation radiant!

As a medical physicist you present complex information in many settings, from team meetings to large conferences. Regardless of the audience, the goal is the same: deliver a clear message that is understood and remembered.

This presentation explores two key ingredients for a radiant presentation. First, less is more. By focusing on the core message and avoiding unnecessary detail, you guide your audience along a clear path rather than a maze. Second, connection matters. Engaging with your audience captures attention, improves understanding, and boosts retention. Together, focus and connection add clarity, personality, and radiance to your presentations.

SESSION – Building intelligence in radiotherapy treatment planning

Radiotherapy treatment planning is inherently a complex decision-making process spanning multiple interconnected tasks, including target and organ delineation, prescription, plan optimization, and quality assurance. In recent years, artificial intelligence has enabled the development of powerful tools that address individual components of this workflow with growing success.

With the emergence of advanced AI decision-making capabilities, particularly foundation models and multi-agent systems, it is now both necessary and feasible to move beyond isolated tools toward building holistic, intelligent treatment planning workflows. This talk overviews this emerging paradigm and highlights recent research efforts that integrate AI across the full planning pipeline.

SESSION – Technology meets biology: dose rates and FLASH – precision and spatial fractionation

Technology development in radiotherapy has given us tremendous advanced in precision and accuracy. However, for curious minds such as physicists’, the next challenge already approaches: can we improve treatments outcomes using biological effects? Preclinical experiments show remarkable results in term of normal tissue sparing and improvements of tumor control, using techniques such as FLASH and spatial fractionation (SFRT).

Moving them to the clinic however requires additional effort – not only from the technology development. I will review in this presentation my experience in implementing FLASH and SFRT in clinical practice, highlighting the challenges still awaiting in this field.

SESSION – MR – guided radiotherapy: from adaptive to biological optimization Magnetic

Resonance-guided radiotherapy (MRgRT) has transitioned from conventional inter-fractional adjustments to real-time online adaptive radiotherapy, enhancing dose escalation and healthy tissue sparing. The current frontier, biological optimization, leverages functional MRI to map tumor heterogeneity and metabolic response.

Central to this paradigm are Quantitative Imaging Biomarkers (QIB); however, their clinical utility depends on rigorous standardization. Without crossplatform reproducibility and validated acquisition protocols, biological data remains prone to inter-vendor variability. Establishing standardized QIBs is essential to move MRgRT from purely anatomical adaptation toward.

SESSION – Automation of brachytherapy workflow: recent advances and implementations

Automation has the potential of rapidly transforming brachytherapy by improving efficiency, robustness, and treatment quality. This talk reviews recent advances and clinical implementations of automated brachytherapy workflows, with a focus on real-time tracking, optimization, and artificial intelligence. Electromagnetic tracking is a good example of an enabler for accurate catheter reconstruction and motion awareness, as well as adaptive workflows.

Similarly multi-criteria optimization frameworks are discussed as powerful tools to efficiently explore patient-specific trade-offs between target coverage and organs-at-risk sparing while minimizing clinical planning time. Finally, emerging artificial intelligence approaches are highlighted for key time-consuming tasks, including workflow orchestration, decision support and others. These technologies are paving the way toward adaptive, more reproducible, and truly patient-specific brachytherapy.
