Registration of intraluminal physiological data to longitudinal image body lumen using extraluminal imaging data

A method comprising:

• receiving, with a processor circuit in communication with the intraluminal imaging device, a plurality of intraluminal images obtained by the intraluminal imaging device during movement of the intraluminal imaging device through a body lumen of a patient;
• receiving, with the processor circuit, a plurality of intraluminal physiology measurements obtained by the intraluminal physiology measurement device during movement of the intraluminal physiology measurement device through the body lumen;
• generating, with the processor circuit, a longitudinal view of the body lumen based on the plurality of intraluminal images;
• generating, with the processor circuit, a graphical representation based on the plurality of intraluminal physiology measurements;
• and
• outputting, to a display in communication with the processor circuit, a screen display comprising:
• the longitudinal view of the body lumen;
• and
• the graphical representation overlaid on the longitudinal view.

A system comprising:

• an intravascular imaging catheter;
• a pressure-sensing guidewire;
• and
• a processor circuit configured for communication with the intravascular imaging catheter and the pressure-sensing guidewire, wherein the processor circuit is configured to:
• receive a plurality of intravascular images obtained by the intravascular imaging catheter during movement of the intravascular imaging catheter through a blood vessel of a patient;
• receive a plurality of intravascular pressure measurements obtained by the pressure-sensing guidewire during movement of the pressure-sensing guidewire through the blood vessel;
• generate a longitudinal view of the blood vessel based on the plurality of intravascular images;
• generate a graphical representation based on the plurality of intravascular pressure measurements;
• and
• output, to a display in communication with the processor circuit, a screen display comprising:
• the longitudinal view of the blood vessel;
• and
• the graphical representation overlaid on the longitudinal view.
