Abstract
(EN)
The present disclosure provides a method for determining a malignancy likelihood score for breast tissue of a patient. The method includes receiving a plurality of two-dimensional images of the breast tissue, the two-dimensional images being derived from a three-dimensional image of the breast tissue, for each two-dimensional image, providing the two-dimensional image to a first model including a first trained neural network, and receiving a number of indicators from the first model, each indicator being associated with a two-dimensional image included in the plurality of two-dimensional images, generating a synthetic two-dimensional image based on the number of indicators and at least one of the plurality of two-dimensional images, providing the synthetic two-dimensional image to a second model including a second trained neural network, receiving a malignancy likelihood score from the second model, and outputting a report including the malignancy likelihood score to at least one of a memory or a display.

La présente divulgation concerne un procédé de détermination d'un score de probabilité de malignité pour un tissu mammaire d'un patient. Le procédé comprend la réception d'une pluralité d'images bidimensionnelles du tissu mammaire, les images bidimensionnelles étant dérivées d'une image tridimensionnelle du tissu mammaire, pour chaque image bidimensionnelle, la fourniture de l'image bidimensionnelle à un premier modèle comprenant un premier réseau neuronal entraîné, et la réception d'un nombre d'indicateurs à partir du premier modèle, chaque indicateur étant associé à une image bidimensionnelle comprise dans la pluralité d'images bidimensionnelles, la génération d'une image bidimensionnelle synthétique sur la base du nombre d'indicateurs et d'au moins l'une de la pluralité d'images bidimensionnelles, la fourniture de l'image bidimensionnelle synthétique à un second modèle comprenant un second réseau neuronal entraîné, la réception d'un score de probabilité de malignité à partir du second modèle, et la délivrance d'un rapport comprenant le score de probabilité de malignité à une mémoire et/ou un dispositif d'affichage.
