In a solid tumor or other cancerous tissue in a human or animal patient, specific objects or conditions serve as indicators, or biomarkers, of cancer and its progress. In a three-dimensional image of the region of interest (Fig .1 element 102), the biomarkers are identified and quantified (Fig. elements 104). Multiple three-dimensional images can be taken over time, in which the biomarkers can be tracked over time (Fig. element 108). Statistical segmentation techniques are used to identify the biomarker in a first image to carry the identification over to the remaining images.

Dans une tumeur solide ou d'autres tissus cancéreux de l'homme ou de l'animal, on peut utiliser des objets ou états spécifiques servant d'indicateurs ou de marqueurs biologiques des cancers et de leur évolution. A cet effet, on identifie et quantifie (104) les marqueurs biologiques dans une image en 3 D d'une zone d'intérêt (102). On peut prendre dans le temps une suite d'images en 3D permettant de suivre l'évolution des marqueurs biologiques (108). On utilise des techniques statistiques de segmentation pour identifier les marqueurs biologiques dans une première image, puis on reporte l'identification dans les images restantes.
