In table above, each top image shows recommended lines for cutting out slices to be submitted for further processing. Bottom image shows which side of the slice that should be put to microtomy. Dashed lines here mean that either side could be used.
Up to the entire specimen may be sliced and submitted if the risk of malignancy is high.[1] Otherwise the rest may be saved in case microscopy indicates further sampling.

- It also shows an example of circular coverage, with equal coverage distance in all four directions.
