Cross-encoded magnetic resonance imaging in inhomogeneous fields
In magnetic resonance imaging (MRI), it is possible to cancel the effects of severe inhomogeneities of the magnetic field even if the field profile is unknown. The new ‘cross-encoded’ method is based on adiabatic frequency-modulated pulses combined with two orthogonal gradients that are applied simultaneously during encoding and decoding. Undistorted two- and three-dimensional images can be obtained in inhomogeneous fields where the breadth of the water resonance extends over several kHz.
