An electrically-powered assembly of devices designed for the production and measurement of hyperpolarized xenon (Xe) gas delivered to the lungs to improve lung magnetic resonance imaging (MRI) during assessment of lung function. It consists of a hyperpolarized xenon generator, a measurement station, and gas delivery equipment. The system includes a wide variety of technologies such as laser-based hyperpolarization, magnetic field generation to slow relaxation of hyperpolarized Xe, and nuclear magnetic resonance (NMR) based measurement of hyperpolarized Xe; it is used with a disposable delivery bag for measured dosing of hyperpolarized Xe to the patient via a mask/mouthpiece.
