A process and osteodensitometry system using a dual-energy cone beam of
X-rays is described. The system comprises an X-ray source capable of
supplying a cone beam of X-rays with at least a first energy called the
high energy and a second energy called the low energy, a two dimensional
X-ray detector and electronic processor for processing images supplied by
the detector. According to the process, a low energy image of a part of
the anatomy of a patient, and a high energy image of the same part of the
anatomy of a patient are acquired, and the images acquired at low energy
and at high energy are matched before building up the map of bone
densities of the part of the anatomy.
