The coronal plane of the zebrafish head reconstructions at different resolutions done using the FBP and the relaxed iteration. The image saturation upper bound has been decreased to ${67}$ % of the maximum intensity of each image to highlight low-intensity details. The scalebar corresbonds to 260 $\mu$ m.(a) FBP, 512-by-512. (b) Relaxed iteration, 512-by-512. (c) FBP, 1024-by-1024. (d) Relaxed iteration, 1024-by-1024.
