Calibration of echo-planar 2D-selective RF excitation pulses

Echo‐planar radiofrequency (RF) pulses (EPP) are increasingly being used for 2D‐selective excitation in MRI. Pulse schemes of this kind are susceptible to eddy‐current effects, timing imperfections, and anisotropy of the gradient system. As a consequence, practical EPP implementations have been rest...
