 Abstract: Multi-Coil shimming is advantageous because of its ease of use for effective local and slice-wise shimming. Shim coils are constructed of current-carrying conductor wires and undergo Lorenz force while placed in the magnet. Currents alteration in slice-wise shimming changes the magnitude and direction of force and imposes mechanical vibrations and acoustic noise. Here we propose strategies to control the level of inter-slice shims current change. The proposed strategies showed that inter-slice shims current change can be appropriately reduced by applying a minor change into shimming routine and without degrading shimming performance significantly.
