Abstract
(EN) A method and system for acquiring the center of gravity of a heart on basis of a CT sequence image. The method comprises: acquiring three-dimensional data of a CT sequence image; and acquiring the center of gravity of a heart according to the three-dimensional data. The center of gravity of a heart is obtained according to the volume ratio of each area of a grayscale histogram to a total area thereof, and the present invention has the advantage of fast and accurate extraction and the effect of a fast calculation speed.
(FR) L'invention concerne un procédé et un système permettant l'acquisition du centre de gravité d'un cœur sur la base d'une image de séquence de tomodensitométrie (CT). Le procédé comprend les étapes consistant à : acquérir des données tridimensionnelles d'une image de séquence CT; et acquérir le centre de gravité d'un cœur en fonction des données tridimensionnelles. Le centre de gravité d'un cœur est obtenu en fonction du rapport de volume de chaque zone d'un histogramme en niveaux de gris sur une surface totale de celui-ci, et la présente invention présente l'avantage d'une extraction rapide et précise et de l'effet d'une vitesse de calcul rapide.
