Figure 1From: Iterative multi-channel radio frequency pulse calibration with improving B1 field uniformity in high field MRI The RF pulse calibration sequence. Three identical RF pulses are applied in sequence at each channel of the transmit coil, and the first spin echo (SE) and the stimulated echo (STE) are acquired to determine the magnitudes and phases of the RF pulses to be applied at the next RF pulse sequence.Back to article page
