Abstract
(EN)
Techniques for diagnosing a patient having an AAA. The techniques include using a computer hardware processor to perform: accessing computed tomography angiography (CTA) images of a portion of the patient, the portion of the patient including the AAA of the patient; providing the CTA images as input to a trained machine learning model, the trained machine learning model being configured to classify a property of the AAA based on the CTA images; and determining, based on the classified property of the AAA, a diagnosis of the patient, the diagnosis including information identifying at least one condition (e.g., an endoleak, an AAA rupture) of the patient.

L'invention concerne des techniques de diagnostic d'un patient ayant un AAA. Les techniques comprennent l'utilisation d'un processeur matériel informatique pour effectuer : l'accès à des images d'angiographie par tomodensitométrie (CTA) d'une portion du patient, la portion du patient comprenant l'AAA du patient; la fourniture des images de CTA en tant qu'entrée à un modèle d'apprentissage automatique entraîné, le modèle d'apprentissage automatique entraîné étant configuré pour classifier une propriété de l'AAA sur la base des images de CTA; et la détermination, sur la base de la propriété classifiée de l'AAA, d'un diagnostic du patient, le diagnostic comprenant des informations qui identifient au moins un état (par exemple une endofuite, une rupture AAA) du patient.
