The 9820 129Xe hyperpolarizer provides a routine supply of high-purity, hyperpolarized 129Xe for gas phase magnetic resonance studies. The polarizer is typically installed near the MRI/NMR suite and processes a custom mixture of unpolarized 129Xe, N2, and 4He, into one or more doses of pure hyperpolarized 129Xe that is available for magnetic resonance studies. There is no chemical change associated with hyperpolarization-only nuclear spin alignment and cryogenic extraction of pure xenon. The hyperpolarized 129Xe is then thawed and dispensed into a container or bag. Once dispensed into an appropriate container, and maintained within a modest holding magnetic field, the polarization relaxes with a T1 of 1-2 hr.

The 3777 upgrade module provides a straightforward means to enhance 129Xe polarization on existing 9800 system by up to a factor of two. Such a doubling of high-purity, hyperpolarized 129Xe polarization improves gas phase magnetic resonance studies by increasing imaging SNR, accelerating workflow or decreasing the volume of xenon required for a study.

The 2881 Polarization Measurement System provides a calibrated measurement of the polarization of hyperpolarized gas. The system includes a Helmholtz pair with power supply, a Q-switched tuned NMR circuit with a precision layer wound 300-turn NMR coil, and a computer equipped with a National Instruments DAQ card for data acquisition, analysis, and storage. No additional equipment is required. A factory calibration to thermally polarized water is standard, with subsequent field calibrations available upon request. Polarization analysis software enables individual polarization measurements as well as automatically measuring polarization over time to accurately measure polarization decay rates.

The Xenon Hyperpolarizer provides a routine supply of high-purity, hyperpolarized xenon gas for MRI for research. The hyperpolarizer is typically installed near the MRI/NMR suite and processes a custom mixture of unpolarized xenon, nitrogen, and helium, into a dose of pure hyperpolarized xenon that is available for MRI. There is no chemical change associated with hyperpolarization–only nuclear spin alignment and cryogenic extraction of pure xenon. The hyperpolarized xenon is then thawed and dispensed into a dose delivery bag. Once dispensed into an appropriate container, and maintained within a modest holding magnetic field, the polarization relaxes with a T1 of 1 to 2 hours.

The Polarization Measurement Station provides a calibrated measurement of the polarization of hyperpolarized gas for research.

No additional equipment is required. A factory calibration to thermally polarized water is standard, with subsequent field calibrations provided by the Polarean technical support team. Polarization analysis software enables individual polarization measurements as well as automatically measuring polarization over time to accurately measure polarization decay rates.

Hyperpolarized xenon is produced by the Xenon Hyperpolarizer from the gas blend of helium (89%), nitrogen(10%), and isotopically enriched xenon (1% total; > 80% isotopic purity xenon) for research. At least one Xenon Gas Blend cylinder is required for the proper operation of the Xenon Hyperpolarization System.

The Gas Handling Manifold is a gas pressure regulation and purification system for research that allows xenon blend cylinders, one ultra-high-purity nitrogen cylinder, and one industrial nitrogen cylinder to be connected to the Xenon Hyperpolarizer.

The dose delivery bags are for individual use only with the Xenon Hyperpolarization System for research. The bag connects to the Xenon Hyperpolarizer and stores the xenon gas mixture until it is ready to be inhaled by the patient. The bag has a clamp to hold the gas inside and a mouthpiece for the patient to inhale the gas. Investigational Device Limited by Federal Law to Investigational Use.
