Methods and apparatus for performing magnetic resonance imaging are disclosed. In one embodiment coil antennas for use with a horizontal field magnetic resonance imaging apparatus are placed in proximity to the scanning region to obtain magnetic resonance images. In accordance with another aspect of the invention the coil antennas are arranged so as to provide zero mutual inductance between the coils so as to increase the sensitivity of the measurement. Additional embodiments include quadrature coil antennas including two antennas, each having their vector fields substantially perpendicular to each other and to a static magnetic field. Methods for using the disclosed antennas in acquiring magnet resonance scans is also disclosed.

Coils for horizontal field magnetic resonance imaging

Multi-slice selectable resolution NMR data acquisition in which multiple slice regions in an object are defined, and the slice regions are excited to emit NMR signals. The NMR signals are spatially encoded, and at least two selected slice regions are excited to emit NMR signals encoded with different spatial resolutions.
