Improved techniques, systems and machine readable programs for magnetic resonance

摘要

Disclosed is a device for inverting the vector direction of at least one set of nuclei contained in a sample. The device includes: a) a controller; b) a power source operably coupled and controlled by the controller; c) an electromagnet in operable communication with the power source controller; d) a sample chamber in electromagnetic communication with the electromagnet; and e) an injector assembly to direct the sample into a magnetic resonance system. The controller is adapted and configured to operate the power source to induce an electromagnetic pulse in the electromagnet to orient the vector direction of nuclei of a sample situated in the sample chamber.
