摘要

铅笔束扫描是一种动态光束传输系统开发的IBA s.a.质子治疗。通过精确控制235mev加速器的光束提取和扫描磁体的光束点运动，可以获得快速而可靠地达到规定的三维剂量分布所需的辐射场。与现有的光束输送系统相比，PBS系统的硬件大大简化，同时提供了准确输送和短治疗时间的可能性。硬件上的简化通过先进的驱动来弥补，这是本文的主题。

Pencil beam scanning: a dynamical approach to proton therapy

Pencil Beam Scanning is a dynamic beam delivery system developed at IBA s.a. for proton therapy. The radiation field necessary to reach in a fast and robust way a prescribed 3D dose distribution is obtained by accurately controlling both the extraction of the beam from a 235 MeV accelerator and the motion of the beam spot thanks to scanning magnets. Compared to existing beam delivery systems, the hardware of the PBS system is considerably simplified while offering the possibility of accurate delivery and short treatment time. The simplification in hardware is compensated for by advanced actuation, which is the topic of the present paper.
