From: Dynamic coronary roadmapping during percutaneous coronary intervention: a feasibility study
Examples of insufficient roadmap and overlay quality. a “Hole“in the map: Some parts of the vessel tree are missing from the roadmap (arrow). b “Blinking“vessel: The coronary artery is displayed discontinuously(circles). c False device tracking: an ICD lead is falsely displayed as a vessel (arrow). d “Jumpy“registration: Exact overlay of the wire and the coronary artery and in the next heartbeat the wire “jumps” and is now displayed next to the vessel (arrows)
