We have improved several components and processes, lasers, cryogenics, and robotics, to produce large quantities of hyperpolarized xenon for medical imaging. Since xenon is inert it can be inhaled, and since it has nuclear magnetism it can be interrogated in an MRI scanner. This talk will outline innovations that enabled a new measurement of the rate of transfer of gas dissolving into the lung parenchyma, revealing functional aspects of the microscopic tissue composition.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>uri physics colloquium Hyperpolarized xenon MRI of lungs F.
