A Compton telescope for dose monitoring in hadron therapy is under development at IFIC. The system consists of three layers of LaBr3 crystals coupled to silicon photomultiplier arrays. (22)Na sources have been successfully imaged reconstructing the data with an ML-EM code. Calibration and temperature stabilization are necessary for the prototype operation at low coincidence rates. A spatial resolution of 7.8 mm FWHM has been obtained in the first imaging tests.

IFIC正在研发一种用于强子治疗剂量监测的康普顿望远镜。该系统由三层与硅光电倍增管阵列耦合的LaBr3晶体组成。已利用ML-EM代码重建数据，成功对(22)Na源进行了成像。对于以低符合率运行的原型来说，校准和温度稳定是必要的。在首次成像测试中获得了7.8毫米半高宽的空间分辨率。
