Portable magnetic resonance imaging methods and apparatus

A portable magnetic resonance imaging system comprising:

• a magnetics system having a plurality of magnetics components configured to produce magnetic fields for performing magnetic resonance imaging, the magnetics system comprising:
• a permanent B0 magnet configured to produce a B0 field for the magnetic resonance imaging system;
• and
• a plurality of gradient coils configured to, when operated, generate magnetic fields to provide spatial encoding of emitted magnetic resonance signals;
• at least one noise reduction system that facilitates operation of the portable magnetic resonance system outside of an electromagnetically shielded room;
• a housing for the B0 magnet, and wherein the at least one noise reduction system comprises at least one electromagnetic shield adjustably coupled to the housing to provide electromagnetic shielding for an imaging region in an amount that is configurable by adjusting the at least one electromagnetic shield about the imaging region;
• a power system comprising one or more power components configured to provide power to the magnetics system to operate the magnetic resonance imaging system to perform image acquisition;
• and
• a base that supports the magnetics system and houses the power system, the base comprising at least one conveyance mechanism allowing the portable magnetic resonance imaging system to be transported to different locations.
