Patent ID: 8554308

Claim:
An examination apparatus for cardiac roadmapping for examination of an object of interest, the examination apparatus comprising: an image processor configured for performing a cardiac roadmapping, the image processor comprising a memory for storing data sets of images of the object of interest and first and second devices, including a vessel-map sequence, and a causal live device-map sequence of the first and second devices, the image processor being configured for performing a registration transform between the vessel-map sequence and the causal live device-map sequence; a determination processor configured for performing a global correlation determination of the vessel-map sequence and the causal live device-map sequence; wherein the global correlation determination is the optimum of the association between the vessel-map sequence and the causal live device-map sequence, based on their overall similarity and temporal coherency, wherein the optimum of the association is deduced at the same time as the registration transform between the vessel-map sequence and the causal live device-map sequence; and a display for displaying images from vessel-map sequences or device-map sequences or both.
