Multi-coil shimming with localized shim coils can
effectively shim high-order B
0
inhomogeneities,
but requires an additional shim coil array outside or
inside the RF coil, which compromises the shimming
performance and/or SNR. To address these limitations, we
recently proposed a new concept that enables parallel RF
excitation/reception and B
0
/B
1
shimming
with a single coil array, thus maximizing both the SNR
and shimming performance, and demonstrated its
feasibility in phantom experiments. Here, we further
validate it in vivo by demonstrating its ability to
perform parallel reception and localized B
0
shimming
in the human brain at 3T, specifically for distortion
correction in DTI.
