Magnetic resonance imaging of laser polarized liquid xenon

We demonstrate magnetic resonance imaging (MRI) of laser polarized liquid x enon, and image exchange between the liquid and vapor phases. The exception ally large magnetization density of this liquid should allow MRI with micro n-scale spatial resolution without signal averaging. Applications may inclu de imaging of density equilibration and convective flow near xenon's liquid -vapor critical point, tow-field imaging of porous media microstructure, an d mapping of the dynamics of two-phase (liquid-gas) flows.
