Abstract
In some aspects, a magnetic system for use in a low-field MRI system. The magnetic system comprises at least one electromagnet configured to, when operated, generate a magnetic field to contribute to a B0 field for the low-field MRI system, and at least one permanent magnet to produce a magnetic field to contribute to the B0 field.
Claims30
A magnetic resonance imaging system comprising:
- a B0 magnet comprising at least one permanent magnet, the B0 magnet configured to generate a magnetic field to contribute to a B0 magnetic field produced at a strength equal to or less than 0.2 T;
- a ferromagnetic yoke configured to capture and direct at least some of the magnetic field generated by the B0 magnet to increase magnetic flux density within an imaging region of the magnetic resonance imaging system;
- at least one gradient coil to provide spatial encoding of magnetic resonance signals;
- at least one power component configured to provide power to the at least one gradient coil;
- a first housing to house the at least one power component, wherein the at least one permanent magnet is outside of the first housing;
- and
- at least one mechanism coupled to the first housing to allow the magnetic resonance imaging system to be transported to different locations.
