Abstract: A method and an apparatus are provided for building a subject-specific statistical model of shape variation for an anatomical structure using a set of geometric representations of shape for the anatomical structure. Each representation is associated with one of multiple subjects, each subject having a respective subset of associated representations, and each subset comprising multiple representations including a reference representation. The multiple representations correspond to different shapes of the anatomical structure arising from physical motion and/or deformation thereof. The method comprises specifying a set of shape parameters whose values, for any given representation, characterize the shape of the representation, and for each subject, representing a probability distribution of the values of the shape parameters across the subset of representations associated with that subject by a set of subject-specific distribution parameters.

Abstract: An embodiment of the invention provides a method and apparatus for registering two medical images with one another. A first medical image including a representation of a biological organ of a subject or for a population is obtained and the surface of the organ is identified in the first medical image. The identified surface is then used to construct a 3D geometric surface model of the organ. The geometric model is used to derive a motion model that incorporates information on the physical material properties of the organ and external forces that cause the organ to move and deform. A second medical image including a representation of the organ of the subject (or another subject, in the case that the first medical image is an atlas image) is obtained and an alignment is determined between a first surface normal vector field for the organ surface, derived from the geometric model, and a second surface normal vector field for the organ surface, derived by filtering the second medical image.
