Abstract

Official abstract text for this publication.

The invention relates to a method for non-invasive reproducible determination of a corrected surface on a 3D bone surface model constructed from 3D medical image of a bone having a deformation consisting in a bump overgrowth at the head-neck junction; wherein said corrected surface comprises: i) a 3D spherical corrected surface patch on the head portion of said 3D bone surface model, and ii) a 3D smooth transition corrected surface patch on the neck portion of said 3D bone surface model, contiguous to said 3D spherical corrected surface patch; Said corrected surface patches are defined by a set of parameters comprising: iii) at least one first parameter (a*) representing a spherical extent value of said 3D spherical corrected surface patch, iv) and a set of at least one second parameter, said set determining the 3D correction boundary of said corrected surface patches, such that said corrected surface patches are continuous with said 3D bone surface model along said boundary.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for non-invasive reproducible determination of a surface on a 3D bone surface model constructed from 3D medical image of a bone having a deformation; the bone comprising a head portion contiguous to a neck portion, and the bone deformation comprising in a bump overgrowth at the head-neck junction; the method comprising: receiving a corrected surface on a 3D bone surface model, wherein said corrected surface comprises: i. a 3D spherical correc…
