data in that portion. The data covering the raw image data space are used to produce a corresponding image of the object.
5357958 INTERVENTIONAL MRI SYSTEM AND RF COILS THEREFORE Leon Kaufman assigned to The Regents of the University of California An MRI RF coil utilizes a helical conductor having a plurality of turns and a non-uniform pitch between turns along at least a portion of the axial length of the coil. The non-uniform pitch is disposed so as to accommodate interventional procedures and/or interventional apparatus (e.g., stereotaxic frames) when used on a human patient in conjunction with magnetic resonance imaging. The nonuniform pitch portion of the coil may comprise a simple gap, an opening formed by deformation or angular disposition of some or all of the coil turns and/or by utilizing fringe field effects of the coil to accomplish at least some of the magnetic resonance imaging procedure.
5357959 ALTERED DIPOLE MOMENT MAGNETIC RESONANCE IMAGING METHOD Royce Fishman ogy Inc
assigned to Praxair Technol-
A diagnostic medical magnetic resonance imaging and quantitative method for use with human and veterinary subjects in the diagnostic evaluation of normal, altered or diseased status of tissues and fluids containing lipids and or proteins by physically combining stable xenon and/or stable krypton in lipid and lipid containing structures in which they are soluble and physically combining stable xenon and/or stable krypton in protein structures comprised of molecules having nuclei with dipole moments which are altered by their physical incorporation of stable xenon and/or stable krypton in their structures when exposed to a magnetic field thus providing positive contrast enhancement to an image produced by magnetic resonance and the ability to quantify and measure physiology by magnetic resonance.
5358703 METHOD FOR THE DETECTION OF NITRIC OXIDE Ching-San Lai assigned to MCW Foundation Inc
Research
A method of detecting nitric oxide in an aqueous body fluid of a mammal comprises introducing into the body fluid the agents required to form a water-soluble, stable, paramagnetic complex with nitric oxide and then subjecting the body fluid to magnetic resonance methods which can detect the complex to determine if any nitric oxide was present. A paramagnetic complex containing nitric oxide also is described, as well as, a method of diagnosing septic shock in a mammal by stabilizing and detecting the presence of nitric oxide in a body fluid of the mammal.
5358704 HEPATOBILIARY TETRAAZAMACROCYCLIC MAGNETIC RESONANCE CONTRAST AGENTS Jean F Desreux, Michael F Tweedle, Peter C Ratsep, Thomas Wagler, Edmund R Marinelli, Angleur, NJ, Belgium assigned to Bristol-Myers Squibb Novel compounds of the formula See Patent for Chemical Structure and metal chelates of the compounds are useful particularly for MRI of the hepatobiliary system.
5359289 MAGNETIC RESONANCE DEVICE Meulen Pete van de:,. Eindhoven, Netherlands assigned to U S Phrhps Corporation In known magnetic resonance devices shimming is applied on the basis of maps of field inhomogeneities obtained from two images of a slice of an object by formation of a ratio image thereof. This ratio image is processed in or&r to obtain shimming information. These known methods are time-consuming and
