The FWHM of the imaged slice width on the single-slice CT/i is plotted above. The slice width remains reasonably close to its axial value up to pitches of around 1, and then starts to broaden out. This is what we predicted for a 2-point interpolation algorithm as used here, as the 2 data points move further apart along the z-axis.
