Iterative multi-channel radio frequency pulse calibration with improving B(1) field uniformity in high field MRI

BACKGROUND: In high field MRI capable of multi-channel radio frequency (RF) transmission, B(1) shimming is a time-consuming job because conventional B(1) shimming techniques require B(1) mapping for each channel. After acquiring the complex-numbered B(1) field maps, the optimal amplitude and phase o...
