Figure 4
Reconstructed image of Elements 1–5 belonging to Group 3 of the 1951USAF pattern, and the sum in pixel intensities measured in this image at locations corresponding to a bar, colored in blue or red color and passing across Elements 1–5 (labeled in green color) or the background, respectively, when (a) no data processing was performed prior to reconstruction; (b) the size of the raw image was enlarged using the resizing factor (see text) prior to reconstruction; and (c) a subpixel analysis approach was performed prior to reconstruction using a 16 µm virtual pixel size. All the raw images corresponding to the reconstructed images shown in this figure were collected under identical conditions (i.e. same distances and acquisition time period).
