这篇我们讲讲核磁弛豫三兄弟中最没有存在感的T2※弛豫，进而分析为什么T2弛豫要用CPMG序列。 核磁共振 序列比较抽象，确实很难理解。 相信有一些同学做了很多次T2实验，至今还不明白CPMG序列，以及为什么要用CPMG序列，如果你也存在这样的疑惑，非常建议您花5分钟的时间，阅读接下来的1500字。 01 T2※弛豫. 理想中的T2弛豫曲线如下图中的蓝色，然而真实情况是：当你施加一个90°脉冲后，采集到的T2弛豫却是这样的（下图中的紫色）。 上篇文章我们说 …

The CPMG (Carr-Purcell-Meiboom-Gill) pulse train is a fundamental component of pulse sequences used for the measurement of dynamic processes by NMR spectroscopy. As reported in his seminal paper of 1950, Hahn discovered that when two successive radio-frequency pulses, separated by a time interval τ, are applied to an ensemble of spins, a ...

2024年9月4日 · 针对上述问题，CPMG（Carr-Purcell-Meiboom-Gill）序列提供了一种更为有效的解决方案。 CPMG序列在X轴方向施加90°脉冲，然后在特定时间间隔施加180°脉冲，以收集回波信号。
