Correct calibration of the transmit field B1+ is crucial to achieve optimal SNR. However, fast and robust B1+ calibration is difficult for X-nuclei due to the low signal sensitivity. In this work, we proposed a fast B1+ calibration method based on the Bloch-Siegert shift and single voxel ISIS localization. With the proposed sequence, the B1+ calibration can be done in less than 5 min for the human brain at B0 = 9.4 T.
