Doses at shallow depths of modulated proton beams delivered by double-scatterers and uniform scanning methods

W. Hsi, G. Zhoa, Z. Li & L. Zuofeng
Same modulation with of proton beams can be delivered by either double-scatterers (DS) or uniform-scanning (US) methods with similar momentum spread at entrance of nozzle. In principle, the characteristics of modulated proton beam should be similar between two delivery methods. However, doses at shallow[for full text, please go to the a.m. URL]
