The kT-point technique exploits the dynamic RF shimming capability of parallel transmission to uniformly excite the spins. That technique allows homogenizing the flip angle in RF-spoiled sequences but also the rotation angle in sequences involving non-selective refocusing pulses. As far as the flip angle is concerned, it has been shown that so-called universal kT-point pulses can be designed to work robustly on any subject without having to tailor the pulse to the subject. In this study we propose to extend the universality concept to refocusing pulses, and to give an experimental demonstration with 3D fast spin echo brain imaging.
