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.

SESSION – Radiation dosimetry in clinical practice:  Challenges and new horizons

Accurate and robust radiation dosimetry is a cornerstone of clinical practice, supporting progress in radiobiological research, radiation therapy, diagnostic imaging, and nuclear medicine. In radiobiological experiments, reliable dose measurement is essential for establishing reproducible dose–response relationships and enabling meaningful biological interpretation and translation to the clinic. In radiation therapy clinical trials, dosimetric accuracy, consistency, and inter‑institutional comparability are critical for treatment standardization, outcome assessment, and patient safety. Similarly, in diagnostic imaging, accurate patient dose estimation underpins optimization strategies aimed at balancing image quality with radiation risk. In the field of radiopharmaceuticals, precise activity calibration and organ dose calculations are fundamental for therapy planning, toxicity assessment, and regulatory compliance.

Central to all these applications is robust reference dosimetry with traceability to national and international measurement standards, ensuring accuracy, reproducibility, and confidence across institutions and technologies. Despite advances in detector systems, computational methods, and hybrid imaging and therapy techniques, significant challenges remain due to complex radiation fields, patient‑specific variability, and evolving clinical workflows. This review discusses current challenges in clinical dosimetry and highlights emerging technologies and methodologies that define new horizons in precision and personalized radiation medicine.

SESSION – Subatomic Strike: The Future of Cancer Treatments with Radionuclides Therapy

Radionuclide therapy is experiencing rapid growth driven by agents such as Lu-177-PSMA-617 and Y-90 microspheres, yet clinical dosimetry and treatment optimization remain largely empirical. This lecture covers emerging approaches that aim to close this gap. We will present probabilistic frameworks that enable practical single-timepoint dosimetry through Bayesian inference on population pharmacokinetic data. Second, we will show mechanistic models of microsphere transport and deposition in liver vasculature for predictive, optimization-driven treatment planning for radioembolization. Finally, we will discuss how track-structure microdosimetry can connect physical dose to biological effect across different radionuclides, including alpha emitters, informing rational isotope selection and combination strategies.

SESSION – Novel MRI Applications Enabled by Magnet Design

The heart of any MRI system is the magnet. This is also typically the costliest component of the overall system. Whereas typical clinical systems in the field strength range 1.5 to 3 Tesla are based on cylindrical magnets made up of superconducting niobium-titanium wire, new applications are emerging that will be enabled by unconventional magnet designs. These applications include low-field permanent magnets that dramatically lower cost and are expected to promote more widespread use in resource-poor locations or provide point-of-care solutions in established healthcare systems. Or new magnet geometries that improve patient access and facilitate interventional procedures guided by MRI. They also include very high field magnets that substantially increase the sensitivity of the MR experiment and open up new potential for capturing metabolic information. This talk will look at the basics of magnet design and how new approaches seek to enable novel MRI applications.

SESSION – How PET technology bridges Science and Patient Care

Positron Emission Tomography (PET) is a powerful imaging technique that translates molecular and metabolic processes into visual data within living organisms. By using radiotracers such as ¹⁸F-FDG and more specialized agents (e.g., PSMA or amyloid tracers), PET enables the study of disease at a cellular level, providing insights beyond traditional anatomical imaging.

Clinically, PET—especially when combined with CT or MR—plays a key role in precision medicine. It improves cancer diagnosis, staging, and treatment monitoring, while also guiding therapies such as planning in radiation oncology. Beyond oncology, PET supports decision-making in cardiology (e.g., assessing heart tissue viability) and neurology (e.g., detecting Alzheimer’s disease and epilepsy).

PET also bridges research and clinical practice by supporting drug development and enabling advanced techniques like total-body imaging or dedicated prototypes (e.g., brain), which enhances sensitivity and reduces radiation exposure. Combined with innovations such as AI-assisted análisis, digital twins and faster scanning technologies, PET continues to improve diagnostic accuracy, patient comfort, and healthcare outcomes.
