Presenting intravascular images and angiographic images co-registered on a display. As an imaging catheter is pushed through an occlusion, a center point of the catheter and an outline of the vessel wall can be displayed. A physician can see where the catheter is crossing the occlusion within the vessel. The physician can determine what path the catheter is taking the through occlusion. Methods include extending an imaging catheter through the occlusion, determining a location of a wall of the vessel relative to a center point of the catheter, obtaining a position of the catheter within a lumen of the vessel via angiography, and displaying the catheter crossing the occlusion by co-registering the location of the wall, the position of the catheter within the lumen, and the lumen on a display. |
