Parrallel-transmit Universal Pulses (UPs) and Fast Online Customized (FOCUS) pulses were trained and evaluated on two different radiofrequency coils. UPs may fail when used on a different coil, whereas FOCUS pulses show a more reliable pulse performance and less dependency on the coil used.
Figure 3 MPRAGE images for a fixed adiabatic inversion pulse and various excitation pulses. Experimental images and corresponding FA simulations are shown for coil-specific CP pulses and all generated pTx excitation pulses.
Figure 4 MPRAGE images using the UP of the respective coil for excitation and various inversion pulses. Experimental images and corresponding FA simulations are shown for coil-specific CP pulses and all generated pTx excitation pulses.
