Abstract

This paper describes a method for detection of the maximum Doppler frequency from a histogram of Doppler signals (HDS). The performance of the system is described, and its behavior in analysis of noise signals that have known lower and upper cut off frequencies is discussed. Experimental investigations show that the device correctly measures the maximum frequency envelope and can be useful in evaluating the maximum flow velocities in the blood circulation system.

摘要

本文描述了一种从多普勒信号直方图（HDS）中检测最大多普勒频率的方法。介绍了该系统的性能，并讨论了其在分析具有已知下限和上限截止频率的噪声信号时的行为。实验研究表明，该设备能够正确测量最大频率包络，可用于评估血液循环系统中的最大流速。
