A universal single-channel pulse was created that improves excitation homogeneity at 3T, for low flip angles. This method does not require subject specific calibration nor a PTX system, thus making it widely applicable. Though even better homogeneity could be achieved through the use of PTX or subject-specific pulse design, in our study the universal single-channel pulse always outperformed the quadrature mode excitation. This could be used to create more uniform contrast in MP-RAGE imaging.
