统计形状分析是通过统计方法从医学图像中获取一组给定形状的几何属性。正颌外科是颅面外科的一种，旨在矫正严重的下颌骨和上颌骨畸形。假设球状拓扑的方法不能表示具有复杂几何和拓扑的解剖结构的类别，包括下颌骨。在本文中，我们提出了一种基于三维几何非刚性变形的方法，将其应用于具有薄而复杂结构的物体。我们能够准确和定量地表征截骨部位的骨愈合以及三个正颌外科病例的髁突重塑，证明了所提出的方法的有效性。
Statistical shape analysis captures the geometric properties of a given set of shapes, obtained from medical images, by means of statistical methods. Orthognathic surgery is a type of craniofacial surgery that is aimed at correcting severe skeletal deformities in the mandible and maxilla. Methods assuming spherical topology cannot represent the class of anatomical structures exhibiting complex geometries and topologies, including the mandible. In this paper we propose methodology based on non-rigid deformations of 3D geometries to be applied to objects with thin, complex structures. We are able to accurately and quantitatively characterize bone healing at the osteotomy site as well as condylar remodeling for three orthognathic surgery cases, demonstrating the effectiveness of the proposed methodology.
