It is a challenge to correct small spatial variations in
B0 inhomogeneities with current B0 shimming
implementations due to a lack of shimming spatial
resolution. Building upon the Integrated Parallel
Reception, Excitation and Shimming (iPRES) concept, this
study improves the spatial resolution by increasing the
number of independent magnetic fields available for each
RF coil. Initial experiments show that the additional
magnetic fields introduced for shimming show a notable
improvement in B0 homogeneity root-mean-square error
relative to the original iPRES design.
