Interslice current change constrained B(0) shim optimization for accurate high-order dynamic shim updating with strongly reduced eddy currents

PURPOSE: To overcome existing challenges in dynamic B(0) shimming by implementing a shim optimization algorithm which limits shim current amplitudes and their temporal variation through the application of constraints and regularization terms. THEORY AND METHODS: Spherical harmonic dynamic B(0) shimm...
