An imaging method and device for the cardiovascular system, the method including the steps of: acquiring a volumetric image having scan planes adjacent to each other of a periodically moving object; identifying at least one time interval of at least one periodic movement of that object; rearranging the scan planes of the volumetric image based on the time interval by combining with each other the scan planes that are in the same time position with respect to the time interval, the object including at least one blood vessel with periodic movements, at least constriction and dilation, and generating and displaying a virtual endo-navigation three-dimensional model by segmenting and reconstructing the volumetric image, the point of view being movable along at least one path, for determining plaques, stenoses or strictures, and/or for analyzing moving structures inside the vessel such as valve leaflets.
