    摘要: The disclosure concerns X-ray scanners and, more particularly, a method to measure the bone density of a patient that takes his or her build into account. The disclosed method consists in performing a calibration of the bone density measurement by means of a phantom that simulates the patient's body and the vertebra an calibration phantom comprising a water insert and an insert with a high concentration of K.sub.2 HPO.sub.4. A measurement is made of the densities of several inserts of different concentrations and of the concentration of the water insert and of the K.sub.2 HPO.sub.4 high concentration insert, in the presence and without the presence of the bag of water, enabling the computation of corrections of the measured density of the patient's vertebra depending on his or her build.
