Abstract:
1. A method for reconstruction of a three-dimensional model of a body structure of a subject, said structure comprising a plurality of objects, wherein (a) bi-dimensional subject-specific detection data of said structure is provided, (b) a knowledge base of said structure is provided, said knowledge base comprising a priori knowledge of the structure, previously established from structures of the same type as the structure to be reconstructed, said knowledge base of structure comprising a knowledge base of each object of said structure, the knowledge base of each object thus comprising a priori knowledge of the respective object, previously established from objects of the same type as the respective object, the knowledge base of said structure being adapted to estimate, from a parameter of any object of the structure, another parameter for at least an object of the structure, (c) a three-dimensional preliminary solution of the structure is obtained, (d) the preliminary solution of at least a first portion of an object is selected from the preliminary solution of the structure, (e) the preliminary solution of at least the first portion of object is modified to be brought in concordance with said subject-specific detection data, (f) at least a three-dimensional subject-specific reconstruction of at least a second portion of object is obtained based on the modified preliminary solution of the first portion of object obtained at step (e), and on the knowledge base of said structure.
