Hyperpolarised xenon production via Rb and Cs optical pumping applied to functional lung MRI
Newton, Hayley Louise (2014) Hyperpolarised xenon production via Rb and Cs optical pumping applied to functional lung MRI. PhD thesis, University of Nottingham.
Hyperpolarisation encompasses a multitude of methods to increase the species' spin polarisation for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) applications. Hyperpolarised 129Xe is produced via spin-exchange optical-pumping (SEOP). Firstly, electronic spins of alkali metal vapour are polarised via absorption of circularly polarised light. Alkali metal polarisation is subsequently transferred to noble gas nuclei via collisions.
