Polarized 129Xe Production by Using the Spin Exchange Optical Pumping Method
CHEBOTARYOVSERGEY,김우영,MILMANEVGENIY,S. Stepanyan 한국물리학회 2013 새물리 Vol.63 No.2
Polarized 129Xe can be used as a gaseous contrast agent for medical resonance imaging (MRI) and which provides better resolution to evaluate lung and other body tissues in vivo. We are developing a setup for 129Xe gas polarization based on the optical-pumping spin-exchange method. The system can produce high quantities of highly-polarized 129Xe atoms and consist of Helmholtz solenoid coils,a high-power diode laser, the optical elements for forming the circularly-polarized laser beam, and “Apollo” nuclear magnetic resonance (NMR) system for measuring the 129Xe polarization level and a vacuum handling system. In this article, we will discuss the current status of our setup.
