Single-sided fast mri gradient field coils and applications thereof

A method for using a magnetic imaging apparatus comprising:

• providing a power source;
• providing a single-sided gradient coil set connected to the power source, the coil set having an aperture,
• wherein the coil set comprises one or more first spiral coils at a first position relative to the aperture and one or more second spiral coils at a second position relative to the aperture, the first position being across from the second position with respect to the aperture;
• and
• turning on the power source so as to flow a current through the one or more first spiral coils and the one or more second spiral coils, thereby generating an electromagnetic field gradient that is projected away from the coil set and into an imaging region of the magnetic imaging apparatus.
