Title
(EN) DEVICE AND METHOD FOR ANALYSIS OF BONE MORPHOLOGY
(FR) DISPOSITIF ET PROCEDE D'ANALYSE DE LA MORPHOLOGIE DES OS
Abstract
(EN)
A method for automatically analyzing the morphometry of bones from data obtained by lateral digital scans of the bone obtains a matrix of data values assembled from an x-ray scan. The matrix (102) is analyzed to locate an axis (108) of the bone (20) from which subsequent measures may be referenced. Once the axis is fixed, one or more of several useful indicia of bone condition such as a length or interbone spacing can be calculated. The measures are compared to a set of reference values that has been normalized to lumbar vertebra of the patient.
(FR)
L'invention porte sur un procédé d'analyse automatique de la morphométrie des os à partir de données obtenues par balayage numérique latéral, fournissant une matrice de valeurs assemblées par balayage aux rayons X. La matrice (102) est analysée pour localiser un axe de l'os à partir duquel les mesures subséquentes peuvent être référencées. Une fois l'axe déterminé, on peut calculer un ou plusieurs éléments relatifs à l'état de l'os, tels que sa longueur ou l'espace interosseux. Les mesures sont ensuite comparées à un jeu de valeurs de référence normalisée, par rapport aux vertèbres lombaires du patient.
