Figure 2
Standard deviation of the reconstructed image when the sample–FZP distance, which was experimentally measured as 50.4 mm, was incrementally modified in post-acquisition prior to performing the reconstruction, (a) firstly from 48.4 to 52.4 mm using a coarse 1 mm step (the reconstructed image obtained for each distance value is also shown), and then (b) from 50.4 to 52.4 mm using a fine 0.1 mm step. In both cases, the optimum distance value that provided the highest image standard deviation (i.e. 51.4 mm) is indicated by a red arrow.
