    Abstract: A dual-tuned hybrid resonator coil for high field multinuclear MRI/MRS combines both the TEM and the BC designs, such that the mode splitting is significantly increased. The coil includes TEM elements and BC coil windows, where the TEM elements are positioned in each of the windows and oriented orthogonally thereto. This arrangement allows retaining all of the advantages of the TEM technology at high frequencies, while drastically reducing mode mixing and the associated shading artifact.

  • Publication number: 20070096731
    Abstract: A series of open-shape nuclear quadrupole resonance (NQR) sensors having environmental noise resilience and a capability for simultaneous independent multi-frequency operation is disclosed. The sensors are multimodal birdcage or TEM-type structures made from single-turn or multi-turn interconnected windows or magnetically coupled elements having uniform distributions of the amplitudes of the corresponding radiofrequency magnetic fields along their surfaces. The phases of these fields change in a cyclical fashion, such that the interference signals are picked up with opposite phases by different parts of the sensors and are, therefore, cancelled out. The devices may have a planar or a curved shape and may or may not be shielded on one side. Planar unshielded sensors may be used to simultaneously detect signals from objects positioned on both of their sides.
