Write the averaged result with skimage.io.imsave 47. The sample container is cylindrical; since it was nearly vertical during the tomography experiment, its trace is a circular ring on each slice. List available plugins. This is extremely poor practice, but otherwise skimage.io.imsave will complain about low-contrast images (and my version of skimage does not implement the check_contrast keyword argument). By default, the different plugins are tried until a suitable candidate is found.
