Bone surface reconstruction using localized freehand ultrasound imaging

We propose a bone surface reconstruction method using localized ultrasound imagery. A set of bone contours is first extracted from a series of freehand 2D B-mode localized images, using an automatic segmentation method. This set is then used to reconstruct the bone surface with a tensor product B-splines approximation. Results of the partial surface reconstruction are shown for real bones and for a phantom physical model.
