Ridge-filter crosstalk in conformal proton FLASH planning: dependence on beamlet pitch and iterative mitigation
Zongsheng Hu, Yuting Li, Henry Meyer +5
Objective: Patient-specific ridge filters (PSRFs) can enable conformal single-energy proton FLASH delivery without energy switching. However, converting optimized spot-based dose d…

Beam modelling of Hitachi PROBEAT proton therapy system for a GPU-based Fast Monte Carlo dose engine
Qianxia Wang, Poenisch Falk, Yao Zhao +8
Background: An in-house dose engine independent of clinic TPS is not only a reliable tool for patient QA verification. More importantly, it plays vital role in cutting-edge researc…

Mimicking large spot-scanning radiation fields for proton FLASH preclinical studies with a robotic motion platform
Fada Guan, Dadi Jiang, Xiaochun Wang +12
Previously, a synchrotron-based horizontal proton beamline (87.2 MeV) was successfully commissioned to deliver radiation doses in FLASH and conventional dose rate modes to small fi…
