INTRALUMINAL TREATMENT GUIDANCE FROM PRIOR EXTRALUMINAL IMAGING, INTRALUMINAL DATA, AND COREGISTRATION

A co-registration system includes a processor circuit that displays one or more intravascular images corresponding to locations along a blood vessel and associated bookmarks within a corresponding x-ray image. The processor circuit receives, from an x-ray imaging device, x-ray images while an intravascular catheter moves through the blood vessel. The processor circuit receives, from the catheter, intravascular data representative of the blood vessel. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. During an imaging phase, the processor circuit generates and displays, based on the coregistered data, bookmarks along the blood vessel. During a later treatment phase, the bookmarks are also displayed in different x-ray images, along with one or more intravascular image corresponding to locations along the blood vessel at which a treatment device is positioned.
