Classification: CPC G | IPC G

Claim 0:
1. An apparatus for producing magnetic resonance images of an object of interest, the apparatus comprising:
one or more arrays of electropermanent magnets in a vicinity of the 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 to change magnetic configurations of the one or more arrays,
wherein magnetic configurations are produced by the one or more electropermanent arrays, and wherein a computer changes the magnetic configurations during one or more spin echoes 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, and
wherein the computer implements net spin magnetization by changing the magnetic configurations during a spin echo using the one or more electropermanent magnet arrays in the vicinity of the object of interest.
