System And Method For DXA Tomo-Based Finite Element Analysis Of Bones

A method of determining various parameters of a bone within the body of a patient, the method comprising the steps of:

• providing a scanning device including at least one x-ray source, at least one x-ray detector and a controller for controlling the movement of the at least one x-ray source and receiving image data from the at least one detector;
• operating the at least one x-ray source at a number of points along at least one plane relative to the patient to obtain a number of dual-energy x-ray images corresponding to the number of points, each point being located at a different angle relative to an axis perpendicular to a detecting surface of the at least one detector;
• reconstructing at least one two-dimensional (2D) planar slice image of the patient utilizing the number of dual-energy x-ray images;
• comparing the at least one 2D planar slice image with a database of images operably connected to the controller;
• and
• modifying a finite element analysis (FEA) model with information provided by the at least one 2D planar slice image.
