Publication number: 20140123681Abstract: An apparatus, system, and method for producing hyperpolarized samples for use in magnetic resonance systems. A sorption pump is incorporated into the apparatus to create a closed system for hyperpolarizing. Being a closed system, the apparatus and system loses no cryogen to atmosphere such that there is no need to replenish cryogen in the system. Under the method, the apparatus is able to operate in three distinct modes.Type: ApplicationFiled: December 11, 2013Publication date: May 8, 2014Applicant: General Electric CompanyInventors: John Arthur Urbahn, Arthur Michael Leach, Jan Henrik Ardenkjaer-Larsen, Ernst Wolfgang Stautner
