To begin, ensure the XENON 129 hyperpolarizer is set up and operational as per the manufacturer's guidelines. Next, use NMR at the Hyperpolarization or HP Measurement Station to conduct T1 relaxation measurements on a representative HP Xenon 129 gas sample. Ensure a direct and efficient route from the Xenon collection point to the Magnet Room designated for imaging to minimize delays during Xenon transportation.
Measure the initial dose equivalent, or DE, of the hyperpolarized Xenon 129 gas before transportation using the displayed equation. Avoid extraneous radio frequency signals along the route as they can contribute to polarization loss. After completing the round trip by transporting the gas from the measurement station into the magnet bore, then back along the same route to the Polarimetry station.
Measure DE again to quantify the anticipated signal loss during gas transport.
