The invention generally relates to intraluminal imaging and methods of tracking one or more portions of a catheter during diagnostic and/or interventional treatment procedures based, at least in part, on a radiolucent feature of the catheter. The invention provides co-registration systems and methods for intraluminal imaging in which a volume of radiolucent negative space within a catheter, generated via translation of a sensor within the catheter, is used to track the location of one or more portions of the catheter, particularly the sensor. Thus, when a vessel is flushed with radiopaque contrast media during angiography, the system provides an improved method of tracking the location of the sensor, which would otherwise be difficult to determine with conventional methods. |
