Dynamic Slice Based shimming at high field is gaining interest. Here, a novel method is presented to measure and characterize EC fields for pre-emphasis and eddy current compensation without the need for field probes or projection based measurements. Complete 3D datasets are acquired providing complete spatio-temporal characterization of eddy field self and cross terms up to third order. Results are used to calibrate a Dynamic Shim Updating (DSU) unit for slice-based applications at 7T.
