摘要 |
A probe, with a longitudinal axis, for use in an NMR system, the probe comprising: (a) a plurality of static magnetic field sources which create a static magnetic field that is non-axisymmetric about the longitudinal axis, in a region outside the probe; and (b) at least one antenna, compromising one or more antennas together capable of creating a time-varying magnetic field which is capable of at least one of exciting nuclei in a sub-region of the region, receiving NMR signals from said excited nuclei and generating NMR electrical signals therefrom; wherein the plurality of magnetic field sources comprise adjacent static magnetic field sources that are magnetized in directions that differ by more than 10 degrees and less than 170 degrees. |
