1. A method comprising:
- providing acquisition data of a patient, comprising at least acquisition data of a bone structure of the patient in a given functional position,providing a knowledge base, comprising at least data related to structures of the same type as the bone structure of the patient,determining, at least from said acquisition data, a patient-specific three-dimensional geometry of the bone structure,determining, from said acquisition data and said knowledge base, patient-specific mechanical characteristics of the bone structure,determining, at least from the acquisition data, a patient-specific position-specific mechanical load applied to the bone structure in said functional given position,assembling the three-dimensional geometry, the mechanical characteristics and the mechanical load into a patient-specific position-specific finite-element model of the bone structure.

Abstract
A method comprising: -providing acquisition data (34,38) of a patient, comprising acquisition data of a bone structure of the patient in a given position, providing a knowledge base (22,43,47), comprising data related to such bone structures, -determining a patient-specific position-specific finite-element model of the bone structure comprising: patient-specific three-dimensional geometry, patient-specific mechanical characteristics of the bone structure, and patient-specific position-specific mechanical load applied to the bone structure in the position.

18. A system comprising:
-
a medical imager adapted to provide acquisition data of a patient, comprising at least acquisition data of a bone structure of the patient in a given position, a knowledge base, comprising at least data related to structures of the same type as the structure of the patient, a computerized unit adapted to determine, from said acquisition data a patient-specific three-dimensional geometry of the bone structure, wherein the computerized unit is further adapted to determine from the acquisition data and said knowledge base, a patient-specific mechanical characteristics of the bone structure, wherein the computerized unit is further adapted to determine, at least from the acquisition data a patient-specific position-specific mechanical load applied to the bone structure in said given functional position, wherein the computerized unit is further adapted to assemble the three-dimensional geometry, the mechanical characteristics and the mechanical load into a patient-specific position-specific finite-element model of the bone structure. - View Dependent Claims (19, 20, 21, 22, 23, 24)
