Building accurate representations of the surfaces of bones in 3D
medical images is an important task in many computer-assisted surgery
procedures. We first present a survey of the existing solutions to
this problem. Then, we give the results of experiments on new 2D and
3D deformable models. We propose to maximize the correlation of raw
image values along contours parallel to the surface of bones. We also
propose new representations of deformable contours: an
orientation-based representation for 2D contours, and an implicit
representation using 4D splines for 3D contours. We finally present
some results of subvoxel segmentation of bone surfaces.
