Hyperpolarized species for NMR/MRI : Laser-polarized xenon

Hyperpolarized species for NMR/MRI : Laser-polarized xenon

Production

  • Animation for PC (S. Jubera)

  • Two optical pumping setups have been built:

    • the first one based on a Titanium:Sapphire laser

    • the second one using laser diodes

Ground state and first excited state of Rubidium and transitions involved in the optical pumping (considering no nuclear spin)
  • Biological applications

Our biological applications of laser-polarized xenon can be sorted in three categories, corresponding to different levels of details:

  1. Molecular scale.

  1. Cellular scale. More…

  2. Anatomic scale. More…

Use of functionalized xenon as a biosensor

Physics of high and out-of-equilibrium magnetization

Series of NMR signal bursts obtained without rf excitation
