Web31 aug. 2013 · The effect of phase correction using homodyne method is illustrated using magnitude and phase images of Susceptibility Weighted Image (SWI) shown in Figure 1 (a). Magnitude image reconstructed from the offline truncated 2D partial -space with fractional lines in the negative phase-encode direction is shown in the top panel (b). Webreconstruction approaches, based on passing the partial data through a phase correcting, finite impulse response (FIR), digital filter are suggested. These FIR and MoFIR …
