We have developed a CsI multidetector probe in order to produce a nuclear ambulatory recorder to study simultaneously cardiac electric activity and the left ventricular ejection fraction. To make the device lighter, the electronics were designed with surface-mounted technology, and a serial data RF transmission system was used. The data are processed on a real-time basis using a portable microcomputer. Unlike other commercially available devices, this monitor avoids the problems of volume, weight, recording time capacity and slow off-line data processing. Our device permits global and regional analysis of the ejection fraction for a moderate manufacturing cost. It is intended primarily for ambulatory use and can easily be adapted to perform a monitoring function. The first tests on patients conducted using the prototype demonstrate the technical reliability and satisfactory operation of the device.
我们研发了一种碘化铯多探测器探头，以制造一种核动态记录器，用于同时研究心脏电活动和左心室射血分数。为使设备更轻便，电子元件采用表面贴装技术设计，并使用了串行数据射频传输系统。数据通过便携式微型计算机进行实时处理。与其他市售设备不同，该监测仪避免了体积、重量、记录时间容量和离线数据处理缓慢等问题。我们的设备以适度的制造成本允许对射血分数进行整体和区域分析。它主要用于动态监测，并且可以轻松地进行调整以执行监测功能。使用该原型对患者进行的首次测试证明了该设备的技术可靠性和令人满意的运行情况。
