FIG. 2.
ky-kz phase-encoding acquisition scheme with eight-fold acceleration using a Poisson-disk undersampling pattern (black: nonsampled). The central 24×8 region is fully sampled for coil sensitivity calibration. k-space edges are skipped to compensate for the additional encoding at the center. Colors encode the position of each sample within the echo train (dark red: early echos, white: late echos). The acquisition parameters for this case are TE=38 ms, echo spacing=7.5 ms, echo train length 13, number of ky points=256, number of kz points=15.
