全身计数器是测最和鉴别人体内放射性的重要工具之一,它在辐射防护、医学研究及疾病诊断中都有着广泛的应用。全身计数器类型很多,然而阴影式屏蔽直线扫描系统是常采用的一种。我们利用这种装置和计算机在线分析技术实现了全身放射性分布的测量。建立了一种全身剖面扫描自动分析方法。
Whole body counter is one of the most important tools to measure and identify radioactivity in human body. It has a wide range of applications in radiation protection, medical research and disease diagnosis. There are many types of full body counters, but shaded mask linear scan systems are often used. We used this device and on-line computer analysis technology to achieve the measurement of the whole body radioactive distribution. A full-body profile scanning automatic analysis method was established.
