摘要： A method and system for detecting an anomaly in a fluid system, comprising exposing a sample of the fluid system to a first, non-oscillating magnetic field, simultaneously exposing the sample to a second, oscillating magnetic field orthogonal to the first field, modulating one or both of the magnetic fields, and detecting and capturing a resulting NMR signal from the sample. An analysis of the captured signal, typically involving transformation of the signal into an NMR frequency domain spectrum, can be performed to look for specific changes in the signal indicative of the presence of a particular anomaly.

摘要： The projection of magnetic gradient fields useful in Magnetic Resonance Imaging where projection of a gradient outside of a field generating assembly allows imaging of samples which will not physically fit inside the coil confines. The linearity of the projected gradient field is improved by arranging the position of the magnetic field generating coil conductors such that the second derivative of a gradient component is equal to zero. In one practical example the linearity is improved by providing a first circular coil which is positioned so that its center is offset along the axis of the field generating coil assembly by a distance equal to half the radius of the coil. In another example a pair of current carrying wires are selectively positioned offset from a region of interest.
摘要翻译：在磁共振成像中有用的磁梯度场的投影，其中在场产生组件外部的梯度的投影允许不会物理地适合线圈限制的样本的成像。通过设置磁场产生线圈导体的位置使得梯度分量的二阶导数等于零，来提高投影梯度场的线性度。在一个实际的例子中，通过提供第一圆形线圈来提高线性度，该第一圆形线圈被定位成使得其中心沿着场产生线圈组件的轴线偏移距离等于线圈半径的距离。在另一示例中，一对载流导线选择性地定位为偏离感兴趣区域。
