The sensitivity of conventional nuclear magnetic resonance (NMR) techniques is
fundamentally limited by the ordinarily low spin polarization achievable in even the strongest …

The nuclear spin polarization of the noble gas isotopes 3He and 129Xe can be increased
using optical pumping methods by four to five orders of magnitude. This extraordinary gain …

Lung imaging has traditionally relied on x‐ray methods, since proton MRI is limited to some
extent by low proton density in the lung parenchyma and static field inhomogeneities in the …

The noninvasive assessment of lung function using imaging is increasingly of interest for the
study of lung diseases, including chronic obstructive pulmonary disease (COPD) and …

Imaging of the lungs in patients with asthma has evolved dramatically over the last decade
with sophisticated techniques, such as computed tomography, magnetic resonance imaging …

Optical polarization of 3He generates large nuclear spin magnetizations, allowing MR
imaging of the gas spaces of human and animal lungs despite the low number density of …

Over a period of well over a decade, a large number and variety of polarized 3 He cells for
neutron applications have been developed and tested at the US National Institute of …

The structure of the excited 2 3 S and 2 3 P triplet states of 3 He and 4 He in an applied
magnetic field B is studied using different approximations of the atomic Hamiltonian. All …
