We describe an NMR method to make a quick determination of average fluid velocity by monitoring the change in phase of the magnetization during a transient signal. We give an example utilizing the second Carr-Purcell-Meiboom-Gill echo in which we measured the velocity of water up to 54 cm/s where each velocity was determined by data taken over 2.5 ms.
我们描述了一种核磁共振方法，通过监测瞬态信号期间磁化强度相位的变化来快速测定平均流体速度。我们给出了一个利用第二次 Carr-Purcell-Meiboom-Gill 回波的例子，在这个例子中我们测量了高达 54 厘米/秒的水流速度，其中每个速度是由在 2.5 毫秒内采集的数据确定的。
