1. A system, comprising:
an intravascular imaging catheter; and
a processor circuit configured for communication with the intravascular imaging catheter and a display, wherein the processor circuit is configured to:
control the intravascular imaging catheter to obtain a first plurality of intravascular images during a pullback of the intravascular imaging catheter through a blood vessel comprising a region of constricted blood flow, wherein the region comprises a target location and a reference location;
identify, from among the first plurality of intravascular images, a first intravascular image obtained at a first location as a candidate to represent one of the target location or the reference location;
output, to the display, a graphical user interface (GUI) for planning a treatment for the constricted blood flow comprising a stent positioned at the target location and the reference location, wherein the GUI comprises a visual representation of first user guidance, wherein the first user guidance comprises stopping the pullback of the intravascular imaging catheter at the first location and instructing the patient to initiate deep breathing;
control the intravascular imaging catheter to obtain a second plurality of intravascular images while the pullback of the intravascular imaging catheter is stopped at the first location and the patient is deep breathing;
determine, in the second plurality of intravascular images, if at least one of a shape or a size of the blood vessel changes at the first location;
accept or reject the first intravascular image as representing the target location or the reference location based on if at least one of the shape or the size of the blood vessel changes at the first location; and
output, via the GUI on the display, a visual representation corresponding to accepting or rejecting the first intravascular image as the representing the target location or the reference location.
