康普顿成像装置已被提出并研究用于广泛的应用。我们开发了一种康普顿相机原型，可以使用基于单片溴化镧 (LaBr3) 晶体与硅光电倍增管 (SiPM) 耦合的两个或三个探测器层进行操作，用于强子治疗中的质子范围验证。在这项工作中，我们展示了我们的原型在放射源实验室测试和模拟研究中获得的结果。 Na-22 和 Y-88 放射源的图像已成功重建。对于距离 5 cm 的 Na-22 源，重建图像的半高全宽低于 4 mm。
Compton imaging devices have been proposed and studied for a wide range of applications. We have developed a Compton camera prototype which can be operated with two or three detector layers based on monolithic lanthanum bromide (LaBr3) crystals coupled to silicon photomultipliers (SiPMs), to be used for proton range verification in hadron therapy. In this work, we present the results obtained with our prototype in laboratory tests with radioactive sources and in simulation studies. Images of a Na-22 and an Y-88 radioactive sources have been successfully reconstructed. The full width half maximum of the reconstructed images is below 4 mm for a Na-22 source at a distance of 5 cm.
