Figure 4
Plots across the cross-correlation images obtained from both zinc fluorescence and differential phase contrast images at per-pixel dwells of 3 and 30 ms. The DPC images show narrower lower-noise cross correlations, especially at lower dose (Fig. 5[link]). Because the same 2 ms shaping time was used for the segmented transmission detector (Hornberger et al., 2008BB10) at both dwell times, there is relatively little improvement of the DPC alignment with increased exposure time in this example measurement.  [article HTML]
