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 (6) being adapted to be evacuated to create a vacuum region, and a cooling device (210, 260) inserted in the central bore or optionally close to the central bore for maintaining a selected temperature of the sample.
