(FR) LOCALISATION DE STRUCTURES ANATOMIQUES DANS DES IMAGES MÉDICALES
Abstract
(EN)
A system (100) includes a computing system (118) with a processor (120) and a computer readable storage medium (122) with computer readable instructions (124) including a localizer (126) with a re-ranker (204). The processor is configured to execute the re-ranker instructions, which causes the re-ranker to receive a plurality of ranked or scored candidate matches, wherein a ranked or scored candidate match includes a set of points of a shape model, and rank the ranked or scored candidate matches based on a predetermined set of features. The shape model represents an anatomical structure of interest.
(FR)
L'invention concerne un système (100), comprenant un système informatique (118) doté d'un processeur (120) et d'un support d’informations lisible par ordinateur (122) doté d'instructions lisibles par ordinateur (124) comprenant un localisateur (126) doté d'un dispositif de reclassement (204). Le processeur est configuré pour exécuter les instructions de dispositif de reclassement, ce qui amène le dispositif de reclassement à recevoir une pluralité de correspondances candidates classées ou évaluées, une correspondance candidate classée ou évaluée comprenant un ensemble de points d'un modèle de forme, et à classer les correspondances candidates classées ou évaluées sur la base d'un ensemble prédéterminé de caractéristiques. Le modèle de forme représente une structure anatomique d'intérêt.
