摘要： A method for obtaining spatially resolved nuclear magnetic resonance chemical shift spectra, by depth-resolved surface coil spectroscopy (DRESS), substantially eliminates surface tissue contamination of the chemical shift spectra by employing selective excitation in the presence of a gradient magnetic field directed coaxial with the axis of a surface coil. The nuclei in a disk-shaped preselected volume are excited by a selective radio-frequency signal pulse applied in the presence of the gradient field. The surface coil is always utilized for receiving magnetic resonance response signals, while the same surface coil, or a separate transmitting antenna, can be used to provide the radio-frequency excitation field across the selected disk-shaped volume. The technique can be combined with conventional 90.degree.-.tau.-180.degree. or 180.degree.-.tau.-90.degree. relaxation time measurement RF pulse sequences, or with a solvent suppression NMR spectroscopy technique employing selective excitation.

摘要： Herein a method for slice selection is provided in an MRI process, the method involves controlling a transmit array by adding low flip angle RF pulses interspersed between refocusing pulses that are used to move a k-space weighting function with respect to one or more B 1 fields used to deposit energy according to a desired k-space weighting function. The low flip angle pulses deposit energy so that an envelope traced by the low flip angle pulses in the k-space weighting function is related to a desired spatially excited region of the sample volume, for example by a Fourier transform, if the phase encoding directions are linear axes that coordinatize the sample volume, and the B 1 fields have linear phase gradients.

摘要： A multicoil NMR data acquisition apparatus and processing method for performing three-dimensional magnetic resonance imaging in a static magnetic field without the application of controlled static magnetic field gradients. A preferred application relates specifically to the detection and localization of groundwater using the Earth's magnetic field. Multicoil arrays are used in both transmit and receive modes, and coherent data processing algorithms applied to the data to generate three-dimensional NMR spin density estimates. Disclosed are methods for acquiring NMR data using an array of at least two transmit and receive coils, and for processing such multicoil data to estimate the three-dimensional NMR spin density distributions.

摘要： Apparatus for obtaining an N.M.R. spectrum comprises two Rf coils (1) and (2), connected to an Rf source (54). Switches (15) and (16) inserted between the Rf coils (1) and (2) and ground at the end of coaxial cables (10) and (11) having a length of 4 allow the coils (1) and (2) to be tuned and detuned at will. The detune switches (15) and (16) essentially eliminate coupling between adjacent coils permitting operation of multiple transmit coils at the same frequency. There are important uses in in-vivo spectroscopy.
