Abstract:
A solenoid for providing a magnetic field to shield hyperpolarized gases and to reduce the depolarization effects on such gases associated with exposure to stray magnetic field gradients or time dependent electromagnetic fields (EMI), comprising:a cylindrical body having at least one coil segment thereon, said cylindrical body sized and configured to receive a container holding a quantity of hyperpolarized gas therein; and a power source operably associated with said at least one coil segment, wherein, in operation, current from said power source is directed into said solenoid at said at least one coil segment to generate a magnetic holding field having a low field strength and sufficient homogeneity to shield a quantity of hyperpolarized gas from stray magnetic field gradients or EMI to thereby reduce the depolarization affects associated therewith.
