Joint dynamic shimming using the scanner’s spherical harmonic shim combined with a local multi-coil shim array

Abstract

In this work, we combined scanner's spherical harmonic shim coils with a local multi-coil shim array to work in parallel for dynamic shimming of the human brain at 9.4 T. Performance of the combined method is compared with global shimming with scanner's built-in shim setup, global shimming with multi-coil and dynamic shimming with multi-coil
