    • A gantry for administering proton beam therapy with improvements which reduce the size, weight, costs and radiation beam loss associated with proton beam therapy systems currently commercially available. The gantry utilizes achromatic superconducting multi-function electromagnet systems wherein the magnets can include dipoles and quadrupoles. The achromatic properties of the rampable magnet systems allow for ease of transmission of the beam whose energy is rapidly changed through a large range of different energies without changing of the strength of the magnetic fields or dipole settings. The magnets may be made with either low or high temperature superconductors. The gantry design further integrates beam scanning but keeps the gantry isocentric. A much greater fraction of the beam can be transmitted through the gantry than with current art, thereby reducing radiation shielding requirements and the demand put on the accelerator to produce large quantities of proton beam.
    • 用于施用质子束治疗的台架,其具有减少与当前可商购的质子束治疗系统相关联的尺寸,重量,成本和辐射束损失的改进。 龙门架采用消色差超导多功能电磁铁系统,其中磁铁可包括偶极和四极。 可倾斜磁体系统的消色差性质允许能量在不改变磁场强度或偶极子设置的情况下通过大范围的不同能量快速变化的光束的传输。 磁体可以由低温或高温超导体制成。 龙门架设计进一步集成了梁扫描,但保持了龙门式的中心。 与目前的技术相比,梁的大部分可以通过机架传输,从而减少辐射屏蔽要求,并且增加对加速器产生大量质子束的要求。
