全身计数器是一种快速、高效测量进入人体放射性核素的综合系统,该系统主要由探测器、屏蔽体和多自由度控制平台组成。多自由度控制平台是一套结构精密、移动精细和刻度精准的机械定位装置,其主要功能为调整活体内照射测量探测器高纯锗探头的移动、水平移动、俯仰移动(360°旋转)和相对倾斜移动,以确保高纯锗探头和人体被测量部位紧密贴合进而提高探测器的探测效
Whole body counter is a rapid and efficient measurement of human radionuclide integrated system, the system is mainly composed of detector, shield and multi-degree of freedom control platform. The multi-degree-of-freedom control platform is a set of mechanical positioning device with precise structure, fine movement and accurate calibration. Its main function is to adjust the movement, horizontal movement and pitch movement (360 ° rotation) of the high purity germanium probe for in-vivo irradiation detector The relative tilt movement to ensure that the high purity germanium probe and the human body parts are measured closely fit and thus improve the detection efficiency of the detector
