本文描述了一种微处理器脑血流阻抗图的自动分析系统．这系统测量由心动周期引起的随着血液容量脉动而变动的阻抗信息，进行取样，量化和循环存贮．通过外接的示波群，由“滚动显示”程序可监视内存内容的取样波形．通过外接的盒式录音机可以录存脑血流图的数字化信号，这系统能对脑血流图信号的医学模型进行分类和识别，并分析其特征值，最后由微型打印机打印出病历．本文讨论了系统的硬件组成和软件设计，并给出了临床的初步结果．
This article describes an automated analysis system for microprocessor cerebral blood flow impedance maps. This system measures the impedance information that varies with the pulse of the blood volume caused by the cardiac cycle, and is sampled, quantified, and stored cyclically. Through the external oscilloscope group, the “scroll display” program can monitor the sampling waveform of the memory contents. Through the external cassette recorder can record the digital signal of cerebral blood flow diagram, the system can classify and identify the medical model of cerebral blood flow signal, and analyze its eigenvalues, and finally print the medical records by the micro-printer. This article discusses the system’s hardware components and software design, and gives the initial clinical results.
