A type of global pulses is proposed that pre-wind the phase of the spin ensemble within a finite frequency range. The resulting phase distribution in the particular frequency range is similar to the one after the combination of excitation and refocusing pulse in a standard spin echo experiment. The result is a spin echo formation after a single excitation pulse. Choosing a small tip angle, most of the longitudinal magnetization is maintained, potentially allowing T2-weighted imaging at low repetition times, e.g. for 3D encoding.
