Abstract:
(EN) The present invention provides a technology for deriving a mathematical function for describing venous and arterial blood flows in the body by using a four-dimensional medical image. A method for analyzing a blood flow by using a medical image according to an embodiment of the present invention comprises the steps of: determining a blood vessel position from four-dimensional medical image data that is obtained by combining three-dimensional image data of a patient's body, captured at predetermined periods; deriving a primary function for arterial and venous functions by using a vascular signal for the head region and a vascular signal for the heart region among vascular signals included in the three-dimensional image data for the blood vessel position determined in the determination step; and deriving a secondary function that is the final function for the arterial and venous functions, by using the primary function and a vascular signal for the neck region.
(FR) La présente invention concerne une technologie permettant de déduire une fonction mathématique permettant de décrire des écoulements sanguins veineux et artériels dans le corps au moyen d'une image médicale en quatre dimensions. Selon un mode de réalisation de la présente invention, un procédé d'analyse d'un écoulement sanguin au moyen d’une image médicale comprend les étapes consistant : à déterminer une position de vaisseau sanguin à partir de données d'image médicale en quatre dimensions qui sont obtenues par la combinaison de données d'images en trois dimensions du corps d'un patient, capturées à des périodes prédéfinies ; à déduire une fonction primaire pour des fonctions artérielles et veineuses à l’aide d’un signal vasculaire pour la région céphalique et d’un signal vasculaire pour la région cardiaque parmi les signaux vasculaires compris dans les données d'images en trois dimensions pour la position du vaisseau sanguin déterminée dans l'étape de détermination ; et à déduire une fonction secondaire qui est la fonction finale pour les fonctions artérielles et veineuses, au moyen de la fonction primaire et d’un signal vasculaire pour la région du cou.
