The majority of researchers investigating hyperpolarized gas MRI as a candidate functional lung imaging modality have used (3)He as their imaging agent of choice rather than (129)Xe. This preference has been predominantly due to, (3)He providing stro

We describe the principle of operation, design implementation, and initial performance of a high production xenon-129 polarizing system. The polarizer is built on the concept of counterflow-polarizing using a high-power spectrally-narrowed laser, a m

Despite a myriad of technical advances in medical imaging, as well as the growing need to address the global impact of pulmonary diseases, such as asthma and chronic obstructive pulmonary disease, on health and quality of life, it remains challenging

Rationale and Objectives Hyperpolarized gases such as 129Xe and 3He have high potential as imaging agents for functional lung magnetic resonance imaging (MRI). We present new technology offering 129Xe production rates with order-of-magnitude improvem

We present a design for a spin-exchange optical pumping system to produce large quantities of highly polarized 129Xe. Low xenon concentrations in the flowing gas mixture allow the laser to maintain high Rb polarization. The large spin-exchange rate b
