论文摘要
我们讨论了在允许磁性偏置场的瞬时大角度重新定位的环境中易耐误差自旋控制的程序。实验室子午线平面中的脉冲，非磁场脉冲的短序列被得出。这些表明具有与已建立的振幅调节的，在高静态场磁共振中使用的振幅调节脉冲相媲美的带 - 引发特性。使用这些子午脉冲，我们证明了质子（$^{1} $ h）核磁共振的稳健$ z $倒置。
We discuss procedures for error-tolerant spin control in environments that permit transient, large-angle reorientation of magnetic bias field. Short sequences of pulsed, non-resonant magnetic field pulses in a laboratory-frame meridional plane are derived. These are shown to have band-pass excitation properties comparable to established amplitude-modulated, resonant pulses used in high, static-field magnetic resonance. Using these meridional pulses, we demonstrate robust $z$ inversion in proton ($^{1}$H) nuclear magnetic resonance near earth's field.
