Radionuclide brachytherapy source system using beta radiation

Radionuclide brachytherapy sources and systems for applying beta radiation to a target region, such as for maintaining functional drainage bubbles or functional drainage holes in an eye, such as reducing intraocular pressure (IOP) of an eye being treated with glaucoma. The systems herein provide substantially uniform doses over specific regions, thereby providing appropriate radiotherapy. 用于将β辐射施加到靶区域的放射性核素近距离放射治疗源和系统，例如用于维持眼睛中功能性引流泡或功能引流孔，例如，降低正在接受青光眼治疗的眼睛的眼内压(IOP)。本文中的系统在特定区域上提供基本上均匀的剂量，从而提供适当的放射治疗。
