Results overview.

All tests results are shown numerically summarized. The mean and standard deviation of the Euclidean distance to the reference positions are depicted (of every 16 registrations per lesion and per variable). The navigation tests (including the rotational-correction test) do not show a mean distance, but a percentage of the correctly navigated lesions, that were ‘on screen’ after navigation (also of every 16 navigations per lesion and variable).
