This article reports on the development of a prototype of a SPECT tomograph system for online dosimetry in BNCT based on LaBr(3)(Ce) scintillation detectors. The setup shielding was optimized to be used in the accelerator based BNCT facility of the University of Birmingham. The system was designed and built. An image of a (241)Am point source was reconstructed. A projection of a phantom with two tumors with 400 microg/g of (10)B was measured at the BNCT facility.
本文报道了一种基于溴化镧（铈）闪烁探测器的用于硼中子俘获治疗（BNCT）在线剂量测定的单光子发射计算机断层扫描（SPECT）断层扫描系统原型的开发情况。对该装置的屏蔽进行了优化，以便在伯明翰大学基于加速器的BNCT设施中使用。该系统经过设计和建造。重建了一个241Am点源的图像。在BNCT设施中测量了一个含有两个肿瘤且硼含量为400微克/克的体模的投影。
