WebUltrahigh–dose rate FLASH radiotherapy (FLASH-RT) is a potentially paradigm-shifting treatment modality that holds the promise of expanding the therapeutic index for nearly any cancer. At the heart of this exciting technology comes the capability to ameliorate major normal tissue complications without compromising the efficacy of tumor killing.
