Nuclear magnetic resonance pulse sequence with refocusing pulses having reduced tipping angle
Abstract:
A method for acquiring nuclear magnetic resonance measurements of a material uses a modified CPMG sequence with a refocusing pulse having a tipping angle less than 180 °. The results of using the shortened refocusing pulse with reduced power requirements are comparable to those obtained with a conventional CPMG sequence.
Abstract(Chinese):

用于获取材料的核磁共振测量的方法使用具有小于180°的倾斜角的重聚焦脉冲的修改的CPMG序列。 使用具有降低的功率要求的缩短的重聚焦脉冲的结果与用常规CPMG序列获得的结果相当。
