Dual‐norm optimization for passive shimming in MRI with constraints on field uniformity and harmonic suppression
The new method effectively ensures overall field uniformity while keeping high-order harmonic components under control during each iteration. Furthermore, compared to the standard linear programming method that requires a full set of shim trays, our method significantly reduces the need for shim tray adjustments. The simulation results indicated that the proposed method simplifies practical operations by minimizing repetitive adjustments and enhancing overall efficiency, providing a viable solution for iterative shimming optimization process.
