Systems and methods are disclosed for processing tubular objects in multi- dimensional images. The processing includes generating representations of tubular objects which enable subsequent analysis. Systems and methods for processing tubular objects in a multi-dimensional image include establishing a seed points in a multi-dimensional image, searching for an extremum point corresponding to a tubular object having a central curve of intensity extrema, and extracting a one-dimensional central track corresponding to the tubular object and extents corresponding to a plurality of cross-sections along the tubular object. A number of embodiments are presented which apply the systems and methods to a variety of imaging applications.

L'invention concerne des systèmes et des procédés servant à traiter des objets tubulaires en images tridimensionnelles. Ce traitement consiste à générer des représentations d'objets tubulaires permettant une analyse ultérieure. Ces systèmes et ces procédés consistent à établir des points-graines dans une image multidimensionnelle, à rechercher un point d'extremum correspondant à l'objet tubulaire possédant une incurvation centrale d'extremum d'intensité et à extraire un trajet central unidimensionnel correspondant à l'objet tubulaire et des lignes correspondant à une pluralité de sections transversales le long de cet objet tubulaire. Plusieurs modes de réalisation permettent d'appliquer ces systèmes et ces procédés à une variété de domaines utilisant les images.
