NUCLEAR MEDICAL IMAGING--SCINTIGRAPHIC IMAGING SYSTEM FOR SMALL ANIMALS

一种成本相对较低的闪烁成像系统正在开发中 这两个都能在小动物身上成功手术 环境和能够开展全方位的核心脏病学 与当代相关的数据采集和处理程序 人体研究。该系统采用平行孔准直成像 形成，由连接到单一位置的NaI(Ti)晶体组成- 灵敏光电倍增管；模拟电子模块 每个闪烁事件的位置；定制设计的校正 用于归一化某些光电倍增管特性的电路 和一台配备了商业广告的Macintosh II个人电脑 为核医学影像设计的软硬件包 采集、处理、分析和显示。

A relatively low-cost scintigraphic imaging system is being developed that is both capable of successful operation in the small-animal environment and able to carry out the full range of nuclear cardiology data acquisition and processing procedures associated with contemporary human studies. The system, with parallel hole collimation for image formation, consists of a NaI (TI) crystal coupled to a single position- sensitive photomultiplier tube; analog electronic modules to compute the position of each scintillation event; custom-designed correction circuitry for normalization of certain photomultiplier characteristics; and a Macintosh II personal computer equipped with a commercial software/hardware package designed for nuclear medicine image acquisition, processing, analysis, and display.
