ABSTRACT:
A method and an apparatus for producing hyperpolarized samples for use in magnetic resonance imaging (MRI) are provided. The apparatus comprises an ultra-compact cryogen-free cryostat structure for use in polarizing a sample of selected material, wherein the cryostat structure comprises a central bore being adapted to be evacuated to create a vacuum region, and a cooling device inserted in the central bore or optionally close to the central bore for maintaining a selected temperature of the sample.
