STS-1型双探头同位素扫描机在鉴定前曾在我院进行了六个月的试用,成功地进行了一百八十余病例的扫描,得到七百余份成功的扫描图,并进行了各种阴性和阳性模型扫描,与其它各种彩色及黑白扫描机进行了对比,在此期间还对该机的操作系统等进行了反复的改进,并对仪器的各项指标作了进一步的调试。这台仪器除具有一般国际上高级扫描机的特点之外,为了克服由于放射性的自然涨落对于扫描图形的影响,还特意在机内的电子运算部分增加了平滑运算的功能,这是我国首次在临床扫描上试用这种数据处理方法,因此这次试用的目的主要有以下几项:1.全面检验该扫描机的各种操作系统
The STS-1 dual-probe isotope scanner had been tested in our hospital for six months prior to the appraisal, successfully carrying out more than 180 cases of scanning, obtained more than 700 successful scans and carried out Various negative and positive model scans, compared with a variety of other color and black-and-white scanners, during which the aircraft operating system has been repeatedly improved, and the instrument for further debugging indicators . In addition to the general international advanced scanner features, in order to overcome the impact of the natural fluctuations due to radioactivity on the scanned graphics, but also specifically in the machine to increase the electronic computing part of the smoothing function, which is the first time in our country In the clinical scan of this data processing method, so the purpose of this trial are the following: 1. A comprehensive test of the scanner operating system
