2D Unfolding of Bone-implant Samples

The 2D unfolding is performed by a radial projection of the relevant feature information onto the implant surface, followed by an angular sampling.

Figure below show:
Top: rendered surface of the implant with bone-implant contact regions superimposed and the unfolded surface IBC. Black dashed lines show the approximate location of the peaks of the threads. The vertical line indicates the corresponding angles in the two images.

Bottom: Rendered surface of the implant with bone tissue volume in the region of interest superimposed and the unfolded surface. White dashed lines show the peaks of the threads. The vertical line indicates the corresponding angles in the two images.
