摘要
The present invention provides a method and apparatus of amplifying the signal of at least one NMR spectrum and of at least one MRI of hyperpolarized xenon. In an embodiment, the invention includes dissolving the hyperpolarized xenon in a liquid via an input membrane, thereby resulting in xenon in liquid phase, encoding information in the longitudinal magnetization of the nuclear spins of the xenon in liquid phase via an encoding coil surrounding an encoding phantom coupled to an output of the input membrane and via an encoding magnet, thereby resulting in encoded xenon, extracting the encoded xenon into the gas phase from the liquid phase via an extraction membrane coupled to an output of the encoding phantom, thereby resulting in encoded xenon in the gas phase, and decoding the encoded information from the encoded xenon in gas phase via a detection coil coupled to an output of the extraction membrane.
