In a human or animal organ or other region of interest, specific objects, such as liver metastases and brain lesions, serve as indicators, or biomarkers, of disease. In a three-dimensional image of the organ, the biomarkers are identified and quantified. Multiple three-dimensional images can be taken over time, in which the biomarkers can be tracked over time. Statistical segmentation techniques are used to identify the biomarker in a first image and to carry the identification over to the remaining images.

Dans un organe humain ou animal ou dans toute autre région d'intérêt, des objets spécifiques, tels que des métastases du foie et des lésions cérébrales servent d'indicateurs ou de biomarqueurs d'une maladie. Dans une image tridimensionnelle dudit organe (102), les biomarqueurs sont identifiés et quantifiés (104). Plusieurs images tridimensionnelles peuvent être prises dans le temps. Grâce à ces images, on peut suivre les biomarqueurs dans le temps. On utilise des techniques de segmentation statistique pour identifier le biomarqueur dans une première image et pour réaliser l'identification sur les images restantes.
