Table 1 Spatial resolution estimates (mean ± one standard deviation) along the x, y, and z direction extracted from the phase images of the sphere phantom, obtained through sub-sampling the dithered dataset using the values of dx and dy given in the left most columns.
From: Cycloidal-spiral sampling for three-modal x-ray CT flyscans with two-dimensional phase sensitivity
