Abstract
A system, method, and computer program products and associated apparatus, to monitor and determine the polarization level of a quantity of hyperpolarized gas during transport. A portable device is configured to transmit an excitation pulse and analyze a response signal in transit to provide a polarization level corresponding to the hyperpolarized gas. Preferably, the monitoring system can provide magnetic field fluctuation feedback to the transport unit and adjust operating current to a solenoid. The system also can compensate for NMR frequency shifts that may appear in the measured response signal to provide a more accurate polarization level or “real” T1 for the hyperpolarized gas.
