Title
(EN) METHOD AND APPARATUS FOR GENERATING QUANTITATIVE DATA FOR BILIARY TREE STRUCTURES
(FR) PROCÉDÉ ET APPAREIL DE GÉNÉRATION DE DONNÉES QUANTITATIVES POUR STRUCTURES D'ARBRE BILIAIRE
Abstract
(EN)
A method (200) and apparatus (1100) for generating quantitative data for biliary tree structures from volumetric medical imaging scan data. The method comprises performing segmentation (230; 300) of a volume of the medical imaging scan data to identify tubular biliary structures within the volume of the medical imaging scan data; for at least one segmented tubular biliary structure within the volume of the medical imaging scan data, computing (240; 800) at least one set of quantitative structural parameters for at least one location along the length of the tubular biliary structure; and outputting (250) quantitative biliary tree data comprising the at least one set of quantitative structural parameters for the at least one segmented tubular biliary structure.
(FR)
L'invention concerne un procédé (200) et un appareil (1100) qui permettent de générer des données quantitatives pour des structures d'arbre biliaire à partir de données de balayage d'imagerie médicale volumétrique. Le procédé consiste : à exécuter une segmentation (230; 300) d'un volume des données de balayage d'imagerie médicale pour identifier des structures biliaires tubulaires dans le volume des données de balayage d'imagerie médicale; à calculer (240; 800), pour au moins une structure biliaire tubulaire segmentée dans le volume des données de balayage d'imagerie médicale, au moins un ensemble de paramètres structuraux quantitatifs concernant au moins un emplacement le long de la longueur de la structure biliaire tubulaire; à sortir (250) des données quantitatives d'arbre biliaire comprenant le ou les ensembles de paramètres structuraux quantitatifs concernant la ou les structures biliaires tubulaires segmentées.
