Abstract: The invention relates to a polarizer for noble gases comprising a glass sample cell and a pressure chanter in which the sample cell is located. High pressure and accompanying broadband or narrow-band lasers can be similarly provided in an optimal manner. To this end, the polarizer is operated at pressures of 30 bar and higher.

Abstract: The invention concerns a device for the determination of the absolute polarisation of alkali metal atoms. The device can inter alia be used for the diagnosis of alkali metal polarisation in a polariser for inert gases. The device includes a detection laser, which together with a &lgr;/4 plate creates circularly polarised light. A sensor for the measurement of the light absorbed by the sample of the polariser is provided. A Helmholtz coil pair serves for the creation of a static magnetic field B0. An oscillating magnetic field is created with an RF coil. A gradient coil serves for the creation of a linear magnetic field gradient. Various optical components are present. An electronic processor effects the determination of the absolute polarisation of the alkali metal atoms. All the said components with the exception of the Helmholtz coils are firmly mounted onto a platform which can be moved parallel to the direction of the B0 field.

Abstract: The present invention relates generally to nuclear magnetic resonance (NMR) techniques for both spectroscopy and imaging. More particularly, the present invention relates to methods in which hyperpolarized noble gases (e.g., Xe and He) are used to enhance and improve NMR and MRI. Additionally, the hyperpolarized gas solutions of the invention are useful both in vitro and in vivo to study the dynamics or structure of a system. When used with biological systems, either in vivo or in vitro, it is within the scope of the invention to target the hyperpolarized gas and deliver it to specific regions within the system.
