本文介绍了一种新的血流成像系统，它结合了传统的脉冲多普勒装置和新研制的自相关器。在该系统中，活体器官的给定横截面内的血流被真实的实时显示。血行的方向及其方差分别用颜色和色调的差异来表示。实验进行了机械和电扫描器使用幻影，并获得了良好的协议与理论。还对正常和患病心脏进行了临床意义的研究，并取得了成功的结果。
A new blood Row imaging system is described that com-bines a conventional pulsed Doppler device and a newly developed autocorrelator. In the system blood flow within a given cross section of a live organ is displayed in real time. The direction of blood Row and its variance are expressed by means of a difference in color and its hue, respectively. Experiments were conducted with a mechanical and an electrical scanner using phantoms, and good agreement with the theory was obtained. Studies on clinical significance have also been carried out for normal and diseased hearts, and successful results have been found.
