Abstract/Summary In high-field clinical MRI, the RF electromagnetic fields within the biological sample become extremely complex, posing substantial challenge in homogeneous excitation and controlled energy deposition. In this study, we demonstrate a novel B1 shimming technique based on a mechanically rotating RF coil and an iterative optimization. Numerical studies show that the new approach can effectively tailor the transmit B1 field and mitigate the tissue heating issue in high-field MRI.
