Abstract: This disclosure provides alternative medical imaging systems and methods for vascular imaging co-registration. Methods include obtaining extravascular imaging data of a portion of a blood vessel including an extravascular image showing an intravascular imaging device disposed within the vessel with an imaging element disposed at a starting location for a translation procedure. The extravascular image also includes an extravascular contrast image showing the portion of the blood vessel with contrast showing a visualized anatomical landmark. Intravascular imaging data is obtained during the translation procedure that includes one or more intravascular images showing a detected anatomical landmark. The starting location and the ending location of the imaging element on the extravascular imaging data is marked, and the predicted location of the detected anatomical landmark on the extravascular imaging data is marked. The predicted location of the detected anatomical landmark is then aligned with the visualized anatomical landmark.

Abstract: Systems and methods for automatic lesion assessment and/or processing imaging data are disclosed. An example intravascular imaging system may include a catheter including an imaging device. A processor may be coupled to the catheter. The processor may be configured to process imaging data received from the imaging device. The processor may be configured to generate a longitudinal section view of a blood vessel from the imaging data received from the imaging device. The processor may be configured to identify a minimum lumen area along the longitudinal section view of the blood vessel, a distal reference point, and a proximal reference. A display unit may be coupled to the processor. The display unit may be configured to show a display including the longitudinal section view of the blood vessel.
