Shim optimization with region of interest-specific Tikhonov regularization: Application to second-order slice-wise shimming of the brain
<strong>Purpose</strong> Slice-wise shimming can improve field homogeneity, but suffers from large noise propagation in the shim calculation. Here, we propose a robust shim current optimization for higher-order dynamic shim updating, based on Tikhonov regularization with a variable regul...
