Abstract

L'invention porte sur des techniques relatives à la mesure de la densité osseuse et de la composition corporelle du type absorptiométrie à rayons X à double énergie (DEXA), capables de photographier le corps d'une personne à être mesurer à travers un moyen de photographie, de manière à acquérir une image bidimensionnelle ou tridimensionnelle pour le type de corps et le positionnement de la personne à mesurer; et à ajuster une dose de rayons x selon une trajectoire de déplacement d'un générateur de rayons x en réponse au type de corps et au positionnement de la personne à mesurer identifié à partir de l'image bidimensionnelle ou tridimensionnelle.
