A new remote afterloading system, developed for low or medium dose rate brachytherapy has been clinically evaluated. With this apparatus, the Micro-Selectron, up to 15 192Ir wires or seeds encapsulated in a plastic tubing can be loaded simultaneously into implants. Improved radiological protection for the medical staff has now been achieved with this apparatus. One hundred and sixty patients have been treated so far with breast implants using remote afterloading. The mean error frequency over the last year was about one error every 10 treatments of which about half could be considered as machine failures. All treatments could, however, be finished by using spare channels of the afterloader. We have found that a set of 45 source assemblies is adequate for the loading of the breast-needle implants performed in our institute. Every 6 to 8 weeks a new set of 192Ir sources is prepared.
一种为低剂量率或中剂量率近距离放射治疗研发的新型遥控后装系统已进行了临床评估。使用这种名为“微型选择器”的设备，最多可将15根封装在塑料管中的铱-192导线或籽源同时装入植入物中。该设备现已为医护人员提供了更好的辐射防护。到目前为止，已有160名患者使用遥控后装技术进行了乳腺植入治疗。过去一年的平均错误发生率约为每10次治疗出现1次错误，其中约一半可被视为机器故障。然而，所有治疗都可通过使用后装设备的备用通道完成。我们发现，一套45个源组件足以用于我们研究所进行的乳腺针植入物加载。每6至8周准备一组新的铱-192源。
