1. Examination apparatus for cardiac roadmapping for examination of an object of interest located in a volume of interest, the examination apparatus comprising a calculation unit adapted for:
- performing a reference map creation of the volume of interest on the basis of a first image sequence of the volume of interest;
performing a device map sequence creation of the volume of interest on the basis of a second image sequence of the volume of interest;
performing a projection of the device map sequence onto the reference map, resulting in a navigation sequence;
wherein the reference map is a static roadmap of the object of interest.

Abstract
According to an exemplary embodiment of the present invention, a cardiac roadmapping technique is provided, in which a static roadmap is built onto which a view of the intervention device is projected at the correct location. This new viewing mode combines the advantages of both roadmapping, i.e. accurate localization, and the advantages of a motion-free view, i.e. maximum readability.
