Abstract

Methods, systems, assemblies, computer program products and devices deliver hyperpolarized gas by: (a) providing a gas delivery valve with at least one gas flow path therein, the valve comprising a valve body and at least one spool held in the valve body; (b) transmitting a pilot command fluid pulse signal to the at least one spool to introduce pressure onto the spool to force the spool to translate an actuation distance in the valve body; and (c) opening and/or closing the at least one gas flow path in response to the transmitted signal to deliver hyperpolarized gas to a subject.
