Flash radiotherapy (Flash-RT) is an innovative technique used in for cancer treatment because it delivers extremely high dose of radiation (>40 Gy/s) to the tumour a very short period time, typically within fraction second. This ultra-fast delivery distinguishes Flash-RT from conventional radiotherapy, which involves over longer time period, often several minutes. Studies conducted cell and preclinical models suggested that may spare normal tissues radiation-related side effects, such as...
