Abstract
(EN)
The present invention provides: a fluid analysis device which displays flow rate vectors such that the tendencies of the flow of a fluid can be easily understood; a method for operating a fluid analysis device; and a fluid analysis program. Representative two-dimensional flow rate vectors, which are representative of a plurality of two-dimensional flow rate vectors obtained by projecting, on a projection plane, three-dimensional flow rate vectors of a plurality of voxels which overlap in the projection direction of the projection plane, said three-dimensional flow rate vectors indicating the flow rate of a fluid in an anatomical structure, are acquired from three-dimensional volume data and displayed. In the three-dimensional volume data, information related to a three-dimensional flow rate vector is provided to each voxel.

La présente invention concerne : un dispositif d'analyse de fluide qui affiche des vecteurs de débit de telle sorte que les tendances de l'écoulement d'un fluide peuvent être facilement comprises ; une méthode pour faire fonctionner un dispositif d'analyse de fluide ; et un programme d'analyse de fluide. Des vecteurs de débit bidimensionnel représentatifs, qui sont représentatifs d'une pluralité de vecteurs de débit bidimensionnels obtenus par projection, sur un plan de projection, des vecteurs de débit tridimensionnel d'une pluralité de voxels qui se chevauchent dans la direction de projection du plan de projection, lesdits vecteurs de débit tridimensionnel indiquant le débit d'un fluide dans une structure anatomique, sont acquis à partir de données de volume tridimensionnel et affichés. Dans les données de volume tridimensionnel, des informations relatives à un vecteur de débit tridimensionnel sont fournies à chaque voxel.
