Abstract: The invention provides for a magnetic resonance imaging system (100, 300). The magnetic resonance imaging system comprises: a subject support (120) configured for moving a subject between a loading position (121) and an imaging position (200); a receive magnetic resonance imaging coil (114) configured for being placed on the subject; and a light detection system (115) comprising at least one ambient light sensor for measuring light data (144). The light detection system is any one of the following: mounted to the main magnet such that the light data is measured from the imaging zone and mounted to the receive magnetic resonance imaging coil. The execution of the machine executable (140) instructions by a processor (130) cause the processor to: move (500) the subject support from the loading position to the imaging position; acquire (502) the light data using the at least one ambient light sensor when the subject support is in the imaging position; determine (504) if the receive magnetic resonance imaging coil is positioned for acquiring magnetic resonance imaging data using the light data; and provide (506) a signal (146) if the receive magnetic resonance imaging coil is positioned for acquiring the magnetic resonance imaging data.

Abstract: Systems and methods for generating hyperpolarized target materials are disclosed. The disclosed systems and methods can include hyperpolarizing a compound then transferring polarization to a target material. The compound can be selected to have nuclear spins. The compound can be further selected to have electron spins that, when exposed to certain electromagnetic radiation, exceed a predetermined level of polarization. The compound can be exposed to such electromagnetic radiation, optically hyperpolarizing the electron spins of the compound. Polarization can then be transferred from the electron spins of the compound to nuclear spins of the compound, at least in part by exposing the compound to a magnetic field. The compound can be exposed to the target material before or after pulverizing the compound to increase the surface area of the compound, thereby facilitating transfer of polarization from the compound to the target material.

Abstract: Die Erfindung betrifft ein supraleitendes Magnetspulensystem mit einer ersten elektrischen Masche (M1) und einer zweiten elektrischen Masche (M2), die in Serie miteinander verschaltet sind, wobei die erste elektrische Masche (M1) in einem ersten Pfad einen HTS(high temperature superconductor)-Spulenabschnitt (A0) und in Serie dazu einen ersten Hauptspulenabschnitt (A1) und in einem zweiten Pfad ein Quenchschutzelement (Q1) umfasst, das die Serienschaltung von HTS-Spulenabschnitt (A0) und erstem Hauptspulenabschnitt (A1) überbrückt. Der erste Hauptspulenabschnitt (A1) umfasst einen Leiter mit supraleitenden Filamenten in einer Matrix. Die zweite elektrische Masche (M2) umfasst einen Nachbar-Hauptspulenabschnitt (A3) mit einen Leiter mit supraleitenden Filamenten in einer Matrix. Der Nachbar-Hauptspulenabschnitt (A3) ist derjenige Hauptspulenabschnitt einer anderen als der ersten elektrischen Masche, der in radialer Richtung nach außen dem ersten Hauptspulenabschnitt (A1) der ersten elektrischen Masche am nächsten liegt. Das Magnetspulensystem ist dadurch gekennzeichnet, dass im Quenchfall die Leiter der Hauptspulenabschnitte (A1, A3, A4) jeweils einen spezifischen Leistungseintrag (LT/2ϖ) 2 * 1/ρ M erzeugen, wobei der spezifische Leistungseintrag des Leiters des ersten Hauptspulenabschnitts (A1) der ersten elektrischen Masche (M1) höher ist als der spezifische Leistungseintrag des Leiters des Nachbar-Hauptspulenabschnitts (A3) der zweiten elektrischen Masche (M2). Somit kann unter Verwendung von HTS-Supraleitermaterial ein Magnetspulensystem bereitgestellt werden, mit dem besonders hohe Feldstärken erzeugt werden können und/oder das eine geringe Baugröße aufweist.
