Figure 2
Reconstructed slices of a modified Shepp-Logan phantom (a) without zero-padding showing interperiod interference and (b) with adequate zero-padding. The dotted line shows where the line profiles in Fig. 4[link] are taken. The grey scale has been adjusted to make the features and artifacts more easily discernible. In this way the ellipse contour (pixel value = 1.0) is saturated.  [article HTML]
