Inhomogeneity of the magnetic field (B0) in the human body, for instance caused by physiological motion (e.g. breathing), can lead to artifacts. Static second order magnetic field shimming even in the absence of breathing cannot provide a uniform magnetic field in large organs such as the liver, particularly at ultra-high field throughout the breathing cycle. We show that in conjunction with static second order shimming, local arrays of shim coils can substantially improve the magnetic field uniformity in the liver at different breathing states.
