The efficacy of laser polarized noble gas Magnetic Resonance (MR) imaging and spectroscopy depends critically on the ability to produce large magnetizations of the gases used. While signal size is directly related to both the polarization and concentration of the gas, sufficient volumes of gas can also allow studies to be done which examine the time dependence of the biological uptake of polarized noble gas. The authors have undertaken MR imaging and spectroscopy studies with Xe and He. These studies have concentrated on the use of high power laser diode arrays (LDAs) as the most practical means to produce large magnetizations. They discuss the technique and optimization of polarized noble gas production for these medical imaging and spectroscopy experiments.
