Abstract

L’invention a pour objet un procédé implémenté par ordinateur pour déterminer la présence d’une lésion coronarienne pour un patient, comprenant une première étape de réception d’au moins une image médicale multiplanaire curviligne ou étirée de tomodensitométrie (scanner X) d’une artère coronaire dudit patient. L’invention se caractérise en ce qu’il comprend en outre une étape de détermination d’une valeur selon la classification CAD-RADS (pour Coronary Artery Disease – Reporting and Data System value ou système de rapports et de données) d’une lésion coronarienne sur ladite image ou sur une partie de ladite image par l’utilisation d’un premier réseau de neurones profond entraîné appliqué directement aux images ou parties d’images détectées.
