Toward quantitative reconstruction of delivered dose in a 3D digital water phantom for electron FLASH-RT via annular-array electron-induced acoustic imaging
Objective. Electron FLASH radiotherapy (FLASH-RT) represents a disruptive radiotherapy modality. It enables high-dose radiation to tumor lesions over an extremely short duration, ensuring therapeutic efficacy while markedly mitigating damage to normal tissues. However, the accurate dosimetry of FLASH-RT is severely cha...
