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

FA-NRMSE performances of (a), UP, SRD-UP, and , …, (ST) and (b) CP on the design database (box plots indicating the minimum, maximum, 25%, 50% (red horizontal line), and 75% quantiles of the FA-NRMSE values) and the test database (5 subjects) (blue stars). Note the absence of box plot for ST as these pulses are defined only for the five test subjects. For the FA-NRMSE performance assessment on the test database, individual performances are represented with blue stars and median FA-NRMSE across the five subjects is represented with the dashed blue horizontal line.
