Abstract

The second Laplace-Beltrami eigenfunction provides an intrinsic geometric way of establishing natural coordinates for elongated 3D anatomical structures obtained from medical images. The approach is used to establish the centerline of the human mandible from CT and provides automated anatomical landmarks across subjects. These landmarks are then used to quantify the growth pattern of the mandible between ages 0 and 20.
