FLASH therapy is a new radiation treatment modality involving ultra-high dose rates (e.g., over 400 times more than the current standard). It is believed to have the potential to revolutionize cancer treatments. Animal studies have shown that FLASH can reduce radiation-induced damage in healthy tissues while achieving similar tumor killing. It is hypothesized that this “FLASH effect” is likely due to a reduction in Oxygenation levels (e.g., hypoxia) in the healthy tissues, but the mechanisms are still not well understood. This work focuses on investigating this effect using theoretical radiobiological modeling.
