A Statistical Robust Approach to Design Parallel Transmit Radiofrequency Excitations in MRI

Figure 5

Median sagittal view of the mean (a) and (b) CV of the flip angle for (from top to bottom) , UP, SRD-UP, and CP. As expected, for all pulses except CP, the mean flip angle is very close to the target. For the CV of the flip angle, it is of interest to note the gain in the performance of SRD-UP as compared to CP (consistent with the result of Figure 2).
