Compensation of B1 variations in vivo requires mapping both the magnitude and the phase of each channel's RF magnetic field. Since the field distribution is strongly dependent on the specific size, shape, and positioning of the tissue, such mapping must be made for each subject. We present a practical method for acquiring these maps within 10 minutes in phantoms and human subjects at 7T.
