Hyperpolarized xenon-129 is potentially the most viable contrast agent to be used for characterizing pulmonary function by MRI. Further improvements in polarizing technology yield production rates of up to 15 liters/hour with 50% polarization. This high production prototype polarizer was relocated to two clinical sites and demonstrated in pilot clinical studies. First fully engineered systems based on this design, XeBox-E10, will be available in 2010 for collaborative research.
