Abstract: The invention concerns a probe head (50) for whole-body nuclear-resonance tomography or local in vivo nuclear-resonance spectroscopy, comprising a high-frequency coil (51) with a series of inductive sections in the form of metal strips (53-60) disposed alternately with capacitative sections in the form of gaps (61-68) along the line of the high-frequency current (I1) in such a way that the lines of force (72) of the magnetic field (H1) generated by the high-frequency coil (51) run parallel to an axis (74) defined by the high-frequency coil (51). The high-frequency coil (51) forms, together with an outer wall (52), a single unit. The number of inductive and capacitative sections is chosen so that it lies just below the limiting value at which a transition occurs in the distribution of the lines of force (71) of the high-frequency electric field (E1) generated by the high-frequency coil (51), the transition being from a first distribution (75), in which between each section (55) and the axis (74) there is a plane (76) in which the strength of the high-frequency electric field (E1) is zero, to a second distribution, in which the strength of the high-frequency electric field (E1), irrespective of the number of inductive sections, is substantially rotationally symmetrical about the axis and increases linearly from the axis towards the high-frequency coil.

Abstract: Embodiments of the invention provide an arrangement where a small detection coil of an NQR system is mounted on the end of a carrier such as a prodder stick, and is then carried by the carrier into the very near vicinity of, and more particularly for example into contact with, a possible target explosive device. Because the detection coil is brought into contact with or into the very near vicinity of the target, the transmitted NQR signals, and the resultant QR response, can be much lower power, to the extent that such a system can be made fully man-portable, and also be much lower cost to manufacture. As a consequence, NQR explosive detections systems may be deployed in larger numbers than has heretofore been possible, thus increasing the certainty of, and hence safety, of landmine detection, and improving clearance rates.

Abstract: Embodiments of the present invention address the problems with previously known MRI enhancement resonators. The embodiments provide capacitances that are sufficiently large to result in resonance frequencies that are sufficiently low for medical MRI applications in devices that are sufficiently small for implantation into the body. Further, the capacitance and resonance frequency of the MRI enhancement resonator may be easily adjusted to particular desired values by selecting corresponding thin-film dielectrics, or thicknesses of such thin-film dielectrics. Moreover, the design and geometry of the embodiments provide MRI enhancement resonators with high Q-factors. The construction and material of such MRI enhancement resonators also yield flexible and biocompatible devices that are appropriate for applications involving implantation into the body.
