摘要:
An interstitial brachytherapy apparatus of the invention delivers radioactive emissions in an asymmetric fashion to target tissue surrounding a surgical extraction site. The apparatus includes an expandable outer surface element defining an apparatus spatial volume, a radiation source disposed within the apparatus volume, and a means for providing predetermined asymmetric isodose curves within the target tissue. In one configuration, asymmetric isodose curves are created in the target tissue by shaping or locating the radiation source so as to be asymmetrically placed with respect to a longitudinal axis of the apparatus. In other configurations, asymmetric radiopaque shielding is provided between the radiation source and the target tissue. A surgical procedure using the apparatus is also described.
摘要(中):
本发明的间质近距离放射治疗设备以不对称方式递送放射性发射以靶向手术提取部位周围的组织。 该设备包括限定设备空间体积的可扩张外表面元件,设置在设备体积内的辐射源以及用于在目标组织内提供预定不对称等剂量曲线的装置。 在一种配置中,通过使辐射源成形或定位以相对于装置的纵向轴线不对称地放置,在目标组织中产生不对称的等剂量曲线。 在其他配置中,在辐射源和目标组织之间提供不对称的不透射线屏蔽。 还描述了使用该设备的外科手术。
