Transmit sense method is explored using the measured B1+ and simulated B1+ on 7T. An unconventional highly coupled coil with slotted shield is used. The experiment is done with a water phantom that has brain-like properties. The simulated B1+ is calculated from the finite-difference time-domain algorithm and the measured B1+ is measured using flash sequence with multiple flip angles. The transmit sense pulse is designed with spiral trajectory with the acceleration factor of 1, 2, 3 and 4.
