Generating accurate tip angles for NMR outside the rotating-wave approximation
Christopher P Bidinosti, Geneviève Tastevin, Pierre-Jean Nacher
The generation of accurate tip angles is critical for many applications of nuclear magnetic resonance. In low static field, with a linear rather than circular polarized rf field, t…
Polarized Helium to Image the Lung
Michèle Leduc, Pierre-Jean Nacher
The main findings of the european PHIL project (Polarised Helium to Image the Lung) are reported. State of the art optical pumping techniques for polarising ^3He gas are described.…
MRI of the lung using hyperpolarized He-3 at very low magnetic field (3 mT)
C. P. Bidinosti, J. Choukeife, G. Tastevin +2
Optical pumping of He-3 produces large (hyper) nuclear-spin polarizations independent of the magnetic resonance imaging (MRI) field strength. This allows lung MRI to be performed a…
In-Vivo NMR of Hyperpolarized Helium-3 in the Human Lung at Very Low Magnetic Fields
Christopher P. Bidinosti, Jamal Choukeife, Pierre-Jean Nacher +1
We present NMR measurements of the diffusion of hyperpolarized helium-3 in the human lung performed at fields much lower than those of conventional MRI scanners. The measurements w…
