The table shows (columns from left to right) the subject number and corresponding histology samples, RMS registration error in millimetres resulting from landmark-based in vivo CT and ex vivo CT, RMS registration error in millimetres between histology and ex vivo CT and the total registration error between in vivo CT and histology calculated as square root of the sum of squares of the errors between individual steps.
