That principle underpins Billy Loo’s PHASER (Pluridirectional High-energy Agile Scanning Electron Radiotherapy) system, developed at Stanford and SLAC and licensed to a startup called TibaRay. An array of high-efficiency linacs generates X-ray beams from many directions at once. Their high output overcomes the inefficiency of electron-to-photon conversion to deliver the dose at FLASH speed. Beam convergence at the tumor and electronic shaping conform the dose in three dimensions, producing uniform coverage with relatively simple infrastructure.
这一策略似乎取得了成功。美国海关与边境保护局已正式批准了新设计，允许其在美国销售。不过，Ultrahuman的旧款设计，例如去年评测过的Ring Air，目前仍被禁止销售。
