摘要
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.
