Patent number: 9279868Abstract: A method and apparatus for producing a hyperpolarized sample material for use in an NMR investigation provides for a cryogenic region having a target material containing a first hyperpolarizable nuclear species, a second hyperpolarizable nuclear species, and a nuclear spin polarizing agent, wherein the first nuclear species has a higher magnetic moment than the second nuclear species. Microwave energy is used to excite electron spin transitions in the polarizing agent in the presence of a magnetic field. The first hyperpolarizable nuclear species is thereby caused to interact with the electron spin system in the polarizing agent and generate hyperpolarization of at least the first nuclear species of the target material. The target material is then subjected to a lowered magnetic field, wherein the lowered magnetic field facilitates polarization transfer by nuclear thermal mixing between the species to thereby hyperpolarize the second nuclear species.Type: GrantFiled: December 21, 2012Date of Patent: March 8, 2016Assignee: Bruker BioSpin GmbHInventors: Joost A B Lohman, Sami Antoine Adrien Jannin, Werner Maas

Patent number: 8825132Abstract: An NMR experiment on hyperpolarizable magnetic nuclei of substrate molecules in a living human or animal body, involves polarizing the substrate molecules by non-hydrogenating para-hydrogen induced polarization (=NH-PHIP) into a singlet/pseudo singlet state in low magnetic field and injecting the substrate molecules into the living body, the body or a part thereof being previously located inside a magnet at low magnetic field. The magnet is switched on to high magnetic field, and in at least part of the substrate molecules, the singlet state/pseudo singlet state is converted into observable magnetization. An MRI or MRS measurement is carried out with the living body or the part thereof, collecting data from the substrate molecules. The NMR experiment is well applicable on hyperpolarized nuclei within a patient, with reduced losses of magnetization due to relaxation processes.Type: GrantFiled: July 4, 2012Date of Patent: September 2, 2014Assignees: Bruker BioSpin GmbH, The University of YorkInventors: Joost Lohman, Simon Benedict Duckett, Gary George Green, Antonio Giuseppe Gianotti
