Abstract
(EN)
The present invention relates to a system and a method for estimating an ASPECT score, which is a factor for identifying a stroke disease from a brain CT image, the method comprising: a pre-processing step of normalizing and standardizing features in an image data set; a separation step of separating each lesion from CT images classified into a supra-ganglion level and a ganglion level; and a determination step of independently constructing a neural network for learning positive/negative images by each lesion, so as to determine whether a lesion indicates a stroke, wherein an ASPECT score, which is an objective index for determining the state of a stroke patient, can be estimated by using a brain CT image of the patient.

L'invention concerne un système et un procédé d'estimation d'un score ASPECT, qui est un facteur pour identifier une maladie liée à un accident vasculaire cérébral à partir d'une image CT du cerveau, le procédé comprenant : une étape de prétraitement consistant à normaliser et à standardiser des caractéristiques dans un ensemble de données d'image ; une étape de séparation consistant à séparer chaque lésion des images CT classées en un niveau supra-ganglionnaire et un niveau ganglionnaire ; et une étape de détermination consistant à construire indépendamment un réseau neuronal pour apprendre des images positives/négatives par chaque lésion, de façon à déterminer si une lésion indique un accident vasculaire cérébral, un score ASPECT, qui est un indice objectif pour déterminer l'état d'un patient atteint par un accident vasculaire cérébral, pouvant être estimé à l'aide d'une image CT du cerveau du patient.
