1. A computer implemented method for performing bone segmentation in imaging data of a section of a body structure, the method comprising:

  • Using a processor,Obtaining the imaging data including a plurality of 2D images of the section of the body structure; and

    Performing a multiphase local-based hybrid level set segmentation on at least a subset of the plurality of 2D images by minimizing an energy functional including a local-based edge term and a local-based region term computed locally inside a local neighborhood centered at each pixel of each one of the 2D images on which the multiphase local-based hybrid level set segmentation is performed, the local neighborhood being defined by a Gaussian kernel whose size is determined by a scale parameter (σ

    );

    Generating a 3D volume including a plurality of 3D subvolumes from the segmented blobs of the secondary segmented image data; and

    Associating an anatomical component to each one of the 3D subvolumes using the anatomical knowledge data relative to thesection of the body structure of the imaging data.
