Patent ID: 7801350

Claim:
Method for radiographic imaging, comprising: (a) introducing, into calculation means, digitized radiological data from signals delivered by means of detection of X-rays and corresponding to pixels of an image of an anatomical part comprising an osseous body having a three-dimensional shape and scanned, in an incidence, with a beam of X-rays having an energy spectrum distributed about at least two energies, the digitized radiological data comprising, for each pixel, coordinates of the pixel in the image and absorptiometry values designed to calculate a bone mineral density of the osseous body, in units of a surface area; and (b) determining a value of a composite index using a processor of a radiographic image display device based on the digitized radiological data, and based on a three-dimensional generic model of said osseous body produced prior to generating the digitized radiological data from the scanned signals; wherein the composite index includes at least one of: an angle of bone geometry of an osseous part, a length of bone geometry of an osseous part, a surface of bone geometry of an osseous part, a volume of bone geometry of an osseous part, a bone mineral density of an osseous part, a mass of an osseous part, a water composition of an anatomical part comprising the osseous body, a fat composition of an anatomical part comprising the osseous body, a bone composition of an anatomical part comprising the osseous body, a section modulus of an osseous part, or moments of inertia of an osseous part.
