Figure 2

[a] Point spread function (PSF) for the spatial response of 16×16 linearly applied phase-encoding, showing the characteristic sin(x)/x or sinc(x) function with decaying sidebands due to the use of a limited or truncated number of phase-encoding steps.

[b] The PSF in [a] displayed as a 2D image scaled to 25% of maximum pixel intensity.

[c] The PSF in [b] shown after application of a Hamming filter. Note that the sidebands have been greatly reduced but at the expense of a ~40% increase in voxel size.
