Method for reconstruction of a three-dimensional model of an osteo-articular structure of a patient, wherein a) bi-dimensional patient-specific image data () of said structure is provided; (d) a preliminary solution, corresponding to a previously established solution model of the structure, is provided () from a base (), said preliminary solution comprising a priori knowledge of the corresponding structure, previously established from structures of the same type, said preliminary solution comprising surface data describing the coordinates of the surface of the solution model, and bulk data describing at least one characteristic of the inside of the solution model; the preliminary solution is modified () to be brought in concordance with said patient-specific image data.

Osteo-articular structure

Method for reconstruction of a three-dimensional model of a body structure of a subject, said structure comprising a plurality of objects, wherein a database () of the structure is provided, the database comprising means to estimate, from a parameter of any object of the structure, another parameter for an object of the structure, a preliminary solution for a first object (L1) is modified to be brought in concordance with subject-specific data (), a reconstruction of the second object (T12) is obtained based on the modified first object and on the database of structure ().

Method for reconstruction of a three-dimensional model of a body structure

A radiographic imaging method for three-dimensional reconstruction in which the three-dimensional shape of a model representing an object is calculated from a geometrical model of the object that is known a priori, and obtained from a confinement volume of the object estimated from a geometrical pattern visible in two images and from knowledge of the positions of the sources. A geometrical model is used that comprises information making it possible using an estimator for the object to establish a geometrical characteristic for the model representing the object.
