To bring FLASH therapy out of the lab and into clinical use, researchers like Vozenin and Loo needed machines capable of delivering fast, high doses with pinpoint precision deep inside the body. Most early studies relied on low-energy electron beams like Favaudon’s 4.5-megaelectron-volt Kinetron—sufficient for surface tumors, but unable to reach more than a few centimeters into a human body. Treating deep-seated cancers in the lung, brain, or abdomen would require far higher particle energies.

向 AI 外包自己的意志我是一个思虑极重的人，因为惧怕风险，所以做决策前喜欢思考再三，找出问题的最优解，然后再行动。而当问题的最优解不是那么显而易见，或者根本就无法评判的时候，我就陷入了选择困难的境地，屡屡纠结各种因素和条件，始终无法行动。换句话说，我是个纠结党。这种特点几乎体现在我的所有行为上。比如「晚饭吃什么」对我来说就是一个世纪难题：食堂太腻、外卖太贵、出门太远是我永远在纠结的三要素；此外各种眼花缭乱的券、折扣、红包也在不断给我的决策增加难度。，这一点在新收录的资料中也有详细论述
