我们开发了一个定量的，实时成像系统的标记化合物在活的植物。该系统由CsI闪烁体（用于将β射线转换为可见光）和图像增强单元（由GaAsP半导体和MCP微通道板组成）组成，用于检测极弱的光。将本系统的图像灵敏度和分辨率与成像板（IP）进行比较，发现本系统的灵敏度（20分钟）比IP高，质量与IP相近。利用该系统，在连续图像中显示了P-32在大豆组织中的易位。
We developed a quantitative, real-time imaging system of labeled compounds in a living plant. The system was composed of CsI scintillator to convert beta-rays to visible light and an image intensifier unit (composed of GaAsP semiconductor and MCP; micro channel plate) to detect extremely weak light. When the sensitivity and resolution of the image of our system was compared with that of an imaging plate (IP), the sensitivity of our system (with 20 minutes) was higher than that of an IP, with similar quality to that of an IP. Using this system, the translocation of P-32 in a soybean plant tissue was shown in successive images.
