国外同位素闪烁扫描仪已经成为医学上常规检查仪器之一。扫描仪的发展和使用在六十年代后期达到高潮,其基本技术日趋成熟,从黑白扫描发展到彩色扫描、光点摄影以及采用双探头结构等。以后的研究主要集中于如何实现断层扫描技术、配合使用电子计算机,以提高诊断效果以及如何缩短扫描时间等方面。七十年代初 X 线轴向断层扫描 Foreign isotope scintigraphy scanner has become one of the conventional medical examination equipment. The development and use of scanners culminated in the late 1960s, and their basic technologies matured from black-and-white scanning to color scanning, spot photography, and dual probe structures. Future research focuses on how to achieve tomography, with the use of electronic computers to improve the diagnostic results and how to shorten the scan time and so on.
