中文摘要:
      本文针对用相控阵超声换能器合成波束提取和处理超声多普勒血流信息的原理和方法进行了较深入的讨论和研究。相应于所获得血流信息的要求,重点介绍了进行多普勒血流实时滚动频谱及功率谱分析的特殊方法。通过谱分析结果与B型二维图像和M型心动图的同步显示可以获得关于心脏及血管血流的动态分布,血流途径、方向和性质,血容量及血流速度等信息,从而可为心脏瓣膜及血管疾病的诊断提供重要依据,使超声检查心脏疾病的手段深入到血液动力学的水平。
英文摘要:
      The principles and methods are more deeply discussed and studied for drawing and processing ultrasonic Doppler blood flow information with synthetical wave beams formed by a phase array of ultrasonic transducers. In accordance with requirements of process of acquired blood flow information, it is laid emphasis on introducing special methods to carry out real time scroll frequency spectrum and power spectrum analysis of Doppler blood flow. By displaying synchronously in combination with the result of spectrum, analysis and B mode 2-dimension images and M mode cardiograms, it will be obtained information about dynamic distribution of the heart and blood vessels. the courses, directions and properties of the blood flow, the blood volume, and the speed of blood flow. thus it can supply important basis for diagnosing diseases of the valves of heart and blood vessel, it raises the ways to be detected diseases of the heart by ultrasound to the level of hemodynamics.
