Illustration of wave-encoded SSFSE imaging. a: Pulse sequence diagram of wave-encoded SSFSE with the first three echoes shown. Wave-encoding gradients were played during the readouts in the phase-encoding gradient axis. b: Illustration of a variable-density sampling pattern for self-calibrated wave encoding. Due to the modulation of wave-encoding gradients, wave-encoded trajectories are curved. c: Variable refocusing flip angles for wave-encoded SSFSE. The refocusing flip angles are controlled by four parameters: initial, minimum, center, and last flip angles.
