Abstract:
1. An apparatus for preparing a solution of a hyperpolarized noble gas in a fluid, comprising: a vessel for receiving the fluid; a reservoir for receiving the hyperpolarized noble gas, the reservoir communicating through a first shutoff valve with said vessel, said reservoir being separated in space from said vessel such that it can be cooled independently of said vessel; a gas inlet port communicating through a second shutoff valve with said reservoir; means for withdrawing said fluid from said vessel independently of said first shutoff valve and said second shutoff valve; a cryogenic bath of liquid gases for freezing said hyperpolarized noble gas; and a magnet selected from the group of magnets consisting essentially of a permanent magnet, an electromagnet, a superconducting electromagnet, and a shimmed NMR spectrometer for applying a magnetic field to said reservoir.
