Abstract
(EN)
The present invention describes a system and method for analysing mammography images. Specifically, the present invention comprises a device for classifying the quality of the position of the breast in the mammography image and a device for classifying the breast density in the mammography image, classifying the risk of the breast density preventing diagnosis of a possible lesion, in which these classification devices are calibrated by training a deep neural network using training mammography images and assessing said images using image generation quality reports. The present invention pertains to the fields of image processing, artificial intelligence, medicine, computer engineering, information technology, biomedical engineering and mammography.

La présente invention concerne un système et un procédé d’analyse d’image de mammographie. Plus particulièrement, la présente invention concerne un classificateur de qualité du positionnement du sein sur l’image de mammographie, un classificateur de densité mammaire sur l'image de mammographie, classifiant le risque que la densité mammaire masque un diagnostic d’une possible lésion, ces classificateurs étant étalonnés à partir de l’entraînement d’un réseau neuronal profond au moyen d'images de mammographie d’entraînement et l’évaluation étant réalisée au moyen d’un rapport de qualité de génération d’image. La présente invention relève des domaines du traitement d’images, de l'intelligence artificielle, de la médecine, du génie informatique, des technologies de l'information, du génie biomédical et de la mammographie.
