一、前言:超声脉冲多普勒技术用于临床研究已有十年历史,但它在临床广泛应用并成为无损伤诊断心血管疾病的有力工具,则是在近几年广泛采用微处理机技术以后的事情。微机的应用使得取样血流信息能以实时频谱的形式显示,并为用外部计算机对血流信号作进一步的分析处理提供了可能性。1982年4月,解放军总医院在国内首次向美国 ATL 公司引进了一台 MK500双功能显象仪(Duplex Imager)。经临床使用证明,超声脉冲多普勒实时频谱显示(M/Q)可以
First, Foreword: Ultrasound pulse Doppler technology for clinical research has been 10 years of history, but it is widely used in clinical and become a powerful tool for non-invasive diagnosis of cardiovascular disease, it is widely used in recent years, microprocessor technology After the event. The application of the microcomputer makes it possible to display the sampled blood flow information in the form of real-time spectrum and provide the possibility for further analysis and processing of the blood flow signal with an external computer. In April 1982, the People’s Liberation Army General Hospital first introduced a MK500 Duplex Imager to ATL in the United States. Proved by clinical use, ultrasound pulse Doppler real-time spectrum display (M / Q) can be
