Abstract
Detecting a vessel region in multiple angiographic image frames and defining a direction that perpendicularly intersects a longitudinal direction of the vessel region to improve co-registration between two imaging modalities. Motion of the vessel region is then detected based on the direction that intersects the longitudinal direction of the vessel region by evaluating positions of the vessel region in the multiple angiographic image frames. The method includes defining an area based on the detected motion and the detected vessel region, detecting a marker of an imaging catheter disposed in the vessel region within the area and performing co-registration based on the detected marker.
