Title:
放射線治療システムのためのエネルギー分解器
Document Type and Number:
Japanese Patent JP6499639
Kind Code:
B2
Abstract:
An energy degrader 400 in a radiation therapy system is disclosed. The energy degrader comprises a first material 411, 413 configured to attenuate energy of a particle beam 401 by virtue of particle scattering, wherein said particle scattering causes spatial emittance growth of said particle beam; and a second material 412 operable to constrain said spatial emittance growth by virtue of particle interactions.
