Patent ID: 8255037

Claim:
A method for cardiac roadmapping for examination of an object of interest located in a volume of interest with an examination apparatus, the method comprising the steps of: creating an object of interest map sequence of the volume of interest on the basis of a first image sequence of the volume of interest; creating a device map sequence of the volume of interest on the basis of a second image sequence of the volume of interest; calculating a device map to object of interest map motion estimation to maximize the similarity between the device map sequence and the object of interest map sequence; creating a static reference map of the volume of interest on the basis of a first image sequence of the volume of interest, wherein the reference map is a static roadmap of the object of interest; calculating a reference motion estimation to bring the object of interest map sequence into registration with the static reference map; performing a motion composition to bring the device map sequence into registration with the static reference map, resulting in a navigation sequence; and displaying the navigation sequence as an image on a display device.
