  • Patent number: 7795867
    Abstract: A method of magnetic resonance analysis of a body having therein at least one molecular species and water is disclosed. The method comprises, subtracting magnetic resonance signals induced by a second radiofrequency pulse sequence from magnetic resonance signals induced by a first radiofrequency pulse sequence followed by a evolution period. The first radiofrequency pulse sequence is selected so as to suppress magnetization for the water while preserving a generally longitudinal magnetization to the at least one molecular species. The second radiofrequency pulse sequence being selected so as to suppress transverse and longitudinal magnetization for both the water and the at least one molecular species.
    Type: Grant

  • Patent number: 7573270
    Abstract: A radiofrequency (RF) resonator for magnetic resonance analysis, the RF resonator comprising: (a) at least two conductive elements, each having a first curvature along a direction perpendicular to a longitudinal axis, the at least two conductive elements being spaced along the longitudinal axis, so that when an RF current flows within the at least two conductive elements in a direction of the longitudinal axis, a substantially homogenous RF magnetic field, directed perpendicular to the longitudinal axis, is produced in a volume defined between the at least two conductive elements.

  • Patent number: 7390671
    Abstract: A method of magnetic resonance analysis of at least one type of molecules present in a solvent, the method comprises (a) applying a first radiofrequency pulse sequence selected so as to initially select a coherence of an order n for the at least one type of molecules in the solvent, wherein n is zero, a positive or a negative integer other than ±1, and thereafter to select an exclusive excitation of the at least one type of molecules in the solvent; (b) measuring at least one magnetic resonance parameter of the solvent; and (c) using the at least one magnetic resonance parameter of the solvent for calculating at least one magnetic resonance parameter of the at least one molecule.
