    摘要： In a magnetic field obtaining apparatus, a measuring part (21) that is sufficiently longer than the width of an area to be measured is disposed on a measurement plane that satisfies z = ±, and scanning in an X' direction perpendicular to the longitudinal direction of the measuring part (21) is repeated while changing an angle ¸ formed by a predetermined reference direction on the measurement plane and the longitudinal direction of the measuring part (21) to a plurality of angles. Assuming that x' is a coordinate parameter in the X' direction, measured values f(x', ¸) obtained by repetitions of the scanning are Fourier transformed so as to obtain g(k x' , ¸) (where k x' is a wavenumber in the X' direction). Then, g(k x' , ¸) is substituted into a predetermined two-dimensional potential obtaining equation so as to obtain Æ (x, y, ±) that indicates a two-dimensional potential on the measurement plane. Accordingly, it is possible to perform high-resolution two-dimensional potential measurement as a result of using the measuring part (21) that is sufficiently larger than the width of an area to be measured.

    摘要： A method for mineral analysis of a sample based on detection of NQR and/or NMR signals from a particular substance within a sample includes; setting a frequency of RF pulses to be approximately equal to one of the NQR or NMR frequencies of the substance; setting a set of parameters of the RF pulses to be optimal for the substance; setting a set of receiving parameters to be optimal for the substance; tuning the probe to maximum sensitivity for the signal detected at predetermined frequency and/or to maximum power transfer efficiency for RF pulses transmitted with the probe; transmitting the RF pulses with the probe at said optimal level during a transmitting period to irradiate the sample and excite an NQR or NMR signal in the substance, if present; detecting and processing NQR or NMR signals emitted by the substance; and calculating the concentration of the substance in the sample.

    摘要： Disclosed is an imaging NMR method in which an object that is to be examined is exposed to a stationary magnetic polarization field (B0) and an electromagnetic alternating field, and nuclear resonant processes which are detected as test signals and are visually represented are induced in the object. Also disclosed is a corresponding device. The invention is characterized by the fact that the stationary magnetic polarization field is provided with at least one spatially limited portion of volume within the object, in which the magnetic flux density is greater than in the remaining portion of the object such that the nuclear resonant processes are induced exclusively in said spatially limited portion of volume, test signals are detected by the nuclear resonant processes which have been induced within the limited portion of volume, the position of said portion of volume is modified at least once in a controlled manner, and the test signals are once again detected from the positionally modified portion of volume.

    摘要： Magnetic resonance apparatus is provided comprising a magnet having a first pair of coils arranged in a plane. The coils are operable in a counter- running manner when in use so as to generate a sensitive volume of magnetic field spaced apart from said plane. The magnetic field in the sensitive volume is arranged to have sufficient uniformity to enable magnetic resonance signals to be obtained from a target when located within the sensitive volume. The magnetic field direction Z is oriented to lie substantially parallel to the planes. The coils are arranged such that the sensitive volume is elongate in a direction X substantially parallel to the planes. A drive system is provided to cause relative movement between the magnet and the target so as to allow the sensitive volume to be moved with respect to the target.

    摘要： Magnetic resonance apparatus is provided comprising a magnet having a plurality of pairs of coils arranged in respective substantially parallel planes. The coils in each pair are operable in a counter-running manner when in use so as to generate a region of magnetic field spaced apart from said planes, having sufficient uniformity to enable magnetic resonance signals to be obtained from a target within the region. The magnetic field has a magnetic field direction Z lying substantially parallel to said planes and each of the coils is elongate in a direction X substantially parallel to said planes.

    摘要： A magnet assembly comprising first and second sets of coils (1, 2) for generating respective magnetic fields, wherein the coils are constructed and arranged such that under working conditions, a first homogeneous region (3) can be generated within the envelope defined by the magnet 10 assembly and a second homogeneous region (4) can be generated outside the envelope, the resultant magnetic field in each region being sufficiently homogeneous to enable a NMR process to be performed on an object in the region.
