Comparison of cell surviving fraction. For the same irradiation conditions (cells, LET, oxygen concentration, and dose), the number of surviving cells is higher (sparing effect) for the ultra-high ...

A research group led by Osaka University has demonstrated for the first time in the world that a newly-developed accelerator achieved high-dose proton irradiation instantaneously, opening the door for ...

Researchers are testing a radiation technique that compresses an entire cancer treatment dose into a fraction of a second, aiming to kill tumors while leaving healthy tissue largely unharmed. FLASH ...
