摘要
报道了基于常温射频直线加速器建成的10 MeV光子FLASH放疗射线源样机,采用高平均电流电子束轰击高速旋转辐射转化靶,在距离靶点1 m远处的固体水模内,X射线剂量率达到80.5 Gy/s,达到未来临床实验与推广所需剂量率阈值。
A normal-conducting S-band linear accelerator based 10 MeV photon FLASH radiotherapy X-raysource prototype was built.By using high-energy,high average current electron beam hitting a rotating target,a highdose rate of 80.5 Gy/s at a source-axis distance of 1 m was successfully obtained,which reaches the threshold forfuture clinical trial.
