ABSTRACT:
Modular expandable hyperpolarizers include a central control module and at least one optical pumping module that can be expandable to a plurality of optical pumping modules that can be separately operated depending on the capacity demands at the production site (hospital, clinic and the like). Methods for producing blended polarized gas products include introducing a pre-packaged pre-mixed amount of a polarizer-ready blend of unpolarized gas. Methods for producing the polarized gas can be carried out at the point of use site and the production run according to patient load. Other methods consider the patient load and automatically schedule the hyperpolarizer to yield the desired polarized gas doses to support the patient and/or MRI/NMR equipment schedule.
