CA 2452547

In a human or animal joint, specific objects serve as indicators, or biomarkers, of joint disease. In a three-dimensional image of the joint (102), the biomarkers are identified and quantified (104). Multiple three-dimensional images can be taken over time (106), in which the biomarkers can be tracked over time (112). Statistical segmentation techniques are used to identify the biomarker in a first image and to carry the identification over to the remaining images.

Selon l'invention, des objets spécifiques servent d'indicateurs, ou biomarqueurs, de la maladie articulaire dans des articulations humaines ou animales. Dans une image tridimensionnelle de l'articulation (102), on identifie et on quantifie (104) les biomarqueurs. De multiples images tridimensionnelles peuvent être prises au fil du temps (106), dans lesquelles on peut suivre les biomarqueurs en fonction du temps (112). L'invention fait appel à des techniques de segmentation pour identifier le biomarqueur dans une première image et pour transposer l'identification aux images restantes.
