国际上最早使用的微型探测器是盖革-缪勒计数器,并用它首次对活体内的肿瘤进行了测试。六十年代以来,它逐步为半导体探测器所代替。七十年代以来,微型半导体探测器已广泛地用于血流动力学、肺功能研究以及食管、胃和眼睛等体内和体表器官的诊断。我们也曾用半导体硅探测器对甲状腺节结进行过测试,效果良好。 The earliest use of the world’s smallest micro-detector Geiger - Muller counter, and use it for the first time in vivo tumors were tested. Since the 1960s, it has been gradually replaced by semiconductor detectors. Since the 1970s, miniature semiconductor detectors have been widely used in hemodynamics, lung function studies and the diagnosis of body and surface organs such as the esophagus, stomach and eyes. We have also tested thyroid nodules using semiconductor silicon detectors that work well.
