摘要：
Systems and methods are provided for controlling coherence of a magnetic resonance signal of spin species. The small difference between hard π pulses and their delta-function approximation is exploited to provide new classes of spin echoes which have applications in nuclear magnetic resonance (NMR) spectroscopy, magnetic resonance imaging (MRI) and magnetic resonance microscopy (MRM), and related spectroscopies of solids, and mixtures of solids and liquids. Systems and methods are also provided for controlling coherence of the resonance signal from pseudospin species.
摘要（中）：
提供了用于控制旋转物质的磁共振信号的相干性的系统和方法。 硬p脉冲与其δ函数近似之间的小差异被用于提供新的自旋回波类别，其具有在核磁共振（NMR）光谱，磁共振成像（MRI）和磁共振显微镜（MRM）中的应用，以及相关的 固体光谱，以及固体和液体的混合物。 还提供了系统和方法来控制来自伪孢子物种的共振信号的相干性。
