Enabling ultra-high dose rate radiotherapy through hybrid lightweight rotary anode design
SSRN · 6557133
The Takeaway
FLASH radiation is the holy grail of cancer treatment, but the hardware usually melts under the extreme heat. This hybrid rotary anode design survives the thermal load, finally making ultra-fast, 'healthy-tissue-sparing' radiation a clinical reality.
From the abstract
Spatially fractionated radiotherapy (SFRT) using microbeam and minibeam irradiation is gaining increasing attention as a potential approach for future ultra-high-dose-rate cancer treatments. Its broader clinical implementation, however, is constrained by the performance limits of compact X-ray sources. In particular, the extreme thermal and mechanical loads associated with FLASH-relevant dose rates exceed the operational capabilities of conventional rotary anode systems.Separating X-ray generati
