1. A method for vascular imaging co-registration, the method comprising:
obtaining extravascular imaging data of a portion of a blood vessel, the extravascular imaging data including:
an extravascular image showing an intravascular imaging device disposed within the vessel, with an imaging element of the intravascular imaging device disposed at a starting location for a translation procedure during which the imaging element is translated within the blood vessel from the starting location to an ending location, wherein during the translation procedure, the imaging element is translated within the blood vessel from the starting location to the ending location at a known speed;
an extravascular contrast image showing the portion of the blood vessel with contrast and showing a visualized anatomical landmark;
obtaining intravascular imaging data from the intravascular imaging device during the translation procedure, the intravascular imaging data including one or more intravascular images showing a detected anatomical landmark;
marking the starting location and the ending location of the imaging element on the extravascular imaging data;
marking a predicted location of the detected anatomical landmark on the extravascular imaging data; and
aligning the predicted location of the detected anatomical landmark with the visualized anatomical landmark;
calculating a path on the extravascular imaging data that the imaging element of the intravascular imaging device will travel during the translation procedure from the starting location to the ending location; and
determining the predicted location of the detected anatomical landmark on the extravascular imaging data using the known speed that the imaging element is translated within the blood vessel from the starting location to the ending location.
