The travelling-wave MRI problem

One of the major limitations in performing MRI imaging with high field strengths (3T or 7T) in humans has been than the resultant magnetic field tends to be spatially inhomogeneous and reconstructed images tend to have areas where signal is lost. This post highlights a recent paper ( Brunner et al., Nature, 2009 ) which shows how these problems can effectively be solved using a remote antenna. Very influential work!
