Magnetic Resonance Imaging Using Strong Magnetic Field Gradients: A Review of the STRAFI Experiments

Abstract

Abstract:

Magnetic Resonance Imaging (MRI) is a valuable experimental method extensively used in chemical and biological research as well as medical diagnostics. It is highly sought after because of its non-invasive nature to examine deep inside the sample. Since its inception nearly 40 years ago, many imaging techniques have been developed to improve image resolution, experimental efficiency, and expand its imaging capability with low gamma nuclei. One method that shows great potential is Stray Field Imaging (STRAFI) since it utilizes the strong gradients in the fringe field of superconducting magnets. This review provides a basic introduction to stray field imaging and will cover fundamental imaging theory, the theory and methods used to execute STRAFI experiments and a brief overview of its applications in research. By providing these details we hope to show the strengths and versatility of the STRAFI experiment where conventional MRI methods may fall short.

Key words: Magnetic resonance imaging (MRI), Stray field imaging (STRAFI), Solid-state NMR application
