轻离子束有几个特点，使它们在放射治疗应用中非常有效。这些包括有利的深度剂量分布、有限的穿透范围和高放射生物学效率。此外，磁扫描方法允许将离子束扩散到复杂肿瘤形状的精确图像。离子扫描系统通常由两个磁体组成，每个磁体独立地扫描水平和垂直方向。本文讨论了一种新型组合式X-Y束扫描磁体的设计，该磁体正在为中西部质子放射治疗研究所开发。
Light-ion beams have several features that make them very effective in radiation therapy applications. These include favorable depth dose distribution, finite penetration range, and high radiobiological efficiency. Moreover, magnetic scanning methods allow one to spread an ion beam to an exact image of a complex tumor shape. The ion scanning system usually consists of two magnets, each scanning horizontal and vertical directions independently. This paper discusses the design for a novel combined X-Y beam scanning magnet which is under development for the Midwest Proton Radiotherapy Institute.
