Classification: CPC G | IPC G

Claim 6:
7. A method for producing magnetic resonance images comprising:
providing one or more arrays of electropermanent magnets in a vicinity of an object of interest, one or more sensors of electromagnetic radiation, and circuitry configured to supply power to, and to control, the one or more arrays and sensors,
producing and changing a magnetic configuration of the one or more arrays from a first magnetic field having a static field and a first encoding gradient to a second magnetic field which is a complete inversion of the first magnetic field to produce echoes, and
reconstructing an image based on the echoes, and
wherein a net spin magnetization is implemented by changing magnetic configurations during a spin echo using one or more electropermanent magnet arrays in the vicinity of the object of interest.
