Examples of semi-automatic segmentation. (a) Tomographic slice through the data volume of the subject with type 1 diabetes. (b) Enlarged area marked by a large red square in (a). Coloured rings mark the segmented nerves calculated by our semi-automated algorithm. (c) 3D rendering of the segmented nerves marked in (b). (d) Enlargement of area marked by small red square in (a). Clusters of regenerated axons are segmented by our semi-automated algorithm. (e) 3D rendering of the segmented nerves clusters segmented in (d). (f) 3D volume rendering of the three axons marked by stars in (d). Note how one axon twists around the other two.
