The mechanism responsible for the “FLASH-effect”, the observed healthy tissue sparing without impacting tumor control when irradiating at ultra-high dose-rates is still highly debated. After a decade of research, several hypotheses emerged, yet, none can expl...

Dose evaluations for brachytherapy have traditionally followed the TG-43 formalism, with its simplifying assumptions of a water-equivalent patient. However, patient-specific model-based dose calculation algorithms (MBDCAs) can offer more accurate doses for tr...

This scientific panel discussion will include 3 NIH-funded researchers investigating predictive models that are in the process of being validated prior to their use in clinical trials. Three medical physicists will describe their models and validation process...

This session will bring together researchers, clinicians, and industry partners engaged in preclinical radiation and imaging studies to discuss strategies for reducing animal use while maintaining scientific rigor. With recent federal guidelines emphasizing t...
