Abstract:
1. A method for determining geometrical properties of a structure of an object of interest displayed in an image, comprising the steps of: (a) generating a deformable surface model of a surface of a training object, wherein the deformable surface model includes a mesh of triangles; (b) generating an extended deformable surface model of the training object by associating additional geometrical information to the generated deformable surface model of the training object, wherein the step of generating an extended deformable surface model includes: (c) adapting the extended deformable surface model to a surface of the object of interest, such that a one-to-one point correspondence is maintained between the extended deformable surface model and the adapted extended deformable surface model; (d) determining the geometrical properties of the structure of the object of interest from the adapted extended deformable surface model according to the associated additional geometrical information; and (e) extracting at least one measurement of interest of the structure based on the determined geometrical properties.
