Abstract
(EN)
A method for calculating a coronary artery calcium score, according to an embodiment of the present invention, comprises the steps of: acquiring a target image for a coronary artery and myocardium before contrast enhancement; identifying the coronary artery included in the target image by using an artificial neural network; and calculating a coronary artery calcium score on the basis of the identified coronary artery, wherein the artificial neural network performs learning on the basis of a training database generated via alignment between a pre-acquired image of a coronary artery and myocardium before contrast enhancement and a pre-acquired image of a coronary artery and myocardium after contrast enhancement.

Selon un mode de réalisation, la présente invention concerne un procédé de calcul d'un score de calcium de l'artère coronaire, qui comprend les étapes suivantes : acquisition d'une image cible d'une artère coronaire et d'un myocarde avant une amélioration de contraste ; identification de l'artère coronaire incluse sur l'image cible à l'aide d'un réseau neuronal artificiel ; et calcul d'un score de calcium de l'artère coronaire sur la base de l'artère coronaire identifiée, le réseau neuronal artificiel effectuant un apprentissage sur la base d'une base de données d'apprentissage générée par l'alignement entre une image pré-acquise d'une artère coronaire et d'un myocarde avant l'amélioration du contraste et d'une image pré-acquise d'une artère coronaire et d'un myocarde après amélioration du contraste.
