Imaging method for the cardiovascular system comprising the following steps: acquiring a volumetric image comprising scan planes adjacent to each other of a periodically moving object; identifying at least one time interval of at least one periodic movement of said object; rearranging said scan planes of said volumetric image on the basis of said time interval, by combining with each other the scan planes that are in the same time position with respect to said at least one interval; said object being composed of at least one blood vessel with periodic movements, particularly constriction and dilation movements, and the method provides the following further steps: generating and displaying a virtual endo-navigation three-dimensional model by segmenting and reconstructing said volumetric image, wherein a point of view is movable along at least one path, for determining plaques, stenoses, structures and/or for analyzing moving structures inside the vessel, characterized in that said identification of said at least one time interval of said at least one periodic movement of said blood vessel occurs by using the methods of comparing said scan planes one with the other and of contemporaneously acquiring an electrocardiogram signal and of contemporaneously acquiring a breathing signal and wherein the scan planes rearranged on the basis of said at least one time interval, identified by using said methods, are weighted summed and wherein said comparing the scan planes one with the other is performed by Spatio-Temporal Imaging Correlation (STIC) using Fourier time analysis or autocorrelation of signal intensity. acquiring a volumetric image comprising scan planes adjacent to each other of a periodically moving object; identifying at least one time interval of at least one periodic movement of said object; rearranging said scan planes of said volumetric image on the basis of said time interval, by combining with each other the scan planes that are in the same time position with respect to said at least one interval; said object being composed of at least one blood vessel with periodic movements, particularly constriction and dilation movements, and the method provides the following further steps: generating and displaying a virtual endo-navigation three-dimensional model by segmenting and reconstructing said volumetric image, wherein a point of view is movable along at least one path, for determining plaques, stenoses, structures and/or for analyzing moving structures inside the vessel, characterized in that said identification of said at least one time interval of said at least one periodic movement of said blood vessel occurs by using the methods of comparing said scan planes one with the other and of contemporaneously acquiring an electrocardiogram signal and of contemporaneously acquiring a breathing signal and wherein the scan planes rearranged on the basis of said at least one time interval, identified by using said methods, are weighted summed and wherein said comparing the scan planes one with the other is performed by Spatio-Temporal Imaging Correlation (STIC) using Fourier time analysis or autocorrelation of signal intensity. generating and displaying a virtual endo-navigation three-dimensional model by segmenting and reconstructing said volumetric image, wherein a point of view is movable along at least one path, for determining plaques, stenoses, structures and/or for analyzing moving structures inside the vessel, characterized in that said identification of said at least one time interval of said at least one periodic movement of said blood vessel occurs by using the methods of comparing said scan planes one with the other and of contemporaneously acquiring an electrocardiogram signal and of contemporaneously acquiring a breathing signal and wherein the scan planes rearranged on the basis of said at least one time interval, identified by using said methods, are weighted summed and wherein said comparing the scan planes one with the other is performed by Spatio-Temporal Imaging Correlation (STIC) using Fourier time analysis or autocorrelation of signal intensity.
