20120025832 | Modular MRI phased array antenna - An antenna configuration for use in a magnetic resonance apparatus, which is designed as phase-controlled array and comprises at least two individual antennas which each comprise at least one conductor loop, one tuning network and one matching network, wherein the tuning network contains at least one tuning capacitance and the matching network contains at least one matching capacitance, and the individual antennas are each combined into separate modules which are positioned on and mounted to a support body and can be removed therefrom in a non-destructive fashion, is characterized in that the individual antennas are connected to each other through decoupling elements, wherein the decoupling elements are mounted to the support body in an undetachable fashion. It is thereby possible to define individual antenna modules which can be arranged in a simple fashion around the measuring volume, are also electromagnetically decoupled from each other, and can be positioned close to the measuring volume in order to ensure that the received MRI image has a maximum, high signal-to-noise ratio. | 02-02-2012 |
20110175611 | Method for NMR spectroscopy or MRI measurements using dissolution dynamic nuclear polarization (DNP) with scavenging of free radicals - A method for sample preparation for magnetic resonance measurements using Hyperpolarization by Dissolution Dynamic Nuclear Polarization, involves preparation of frozen beads of a first kind containing paramagnetic substances in addition to the solute under investigation; insertion of the frozen beads into a polarizing magnet; creation of enhanced polarization of nuclei in a magnetic field; heating of the sample to room temperature; transfer of the sample to an MR magnet; and carrying out an MR measurement. In addition, frozen beads of a second kind containing a reducing agent are prepared and inserted into the polarization magnet together with the frozen beads of the first kind. By this method, longitudinal and transverse relaxation times in NMR are extended and free radicals in hyperpolarized solutions are eliminated. | 07-21-2011 |

20110001477 | Method for nuclear magnetic resonance (NMR) spectroscopy measurements using long-lived coherences (LLC) - A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S | 01-06-2011 |
20110001475 | Methods for nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) measurements using long-lived states - A method for nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) measurements, includes creation of enhanced polarization of nuclei of a first kind within a sample in a magnetic field at cryogenic temperatures and transfer of the polarised sample to room temperature. The enhanced polarization of nuclei of the first kind is thereby transformed into long-lived states (LLS) of nuclei of a second kind and these LLS are sustained. The LLS is at least partially converted into observable magnetisation and an NMR or MRI measurement is carried out. The method allows one to extend the time needed between hyperpolarised magnetisation and NMR detection. | 01-06-2011 |
