Figure 3

Reconstructed axial (left), sagittal (central left), and coronal (central right) planes of the sphere phantom, and the corresponding line spread functions (right) extracted from the sphere edges indicated with corresponding colours along the x, y and z axes. Results are shown for a cycloidal-spiral sub-sampling with dx = dy = 20 μm (a–d); a rotation-only sub-sampling, i.e., dx = dy = 0 μm (e–h); the fully sampled (dithered) case (scan duration of 7.5 h) (i–l); a cycloidal-spiral flyscan performed with dx = dy = 20 μm (scan duration of 200 s) (m–p).
