1. An imaging system, comprising:
an intravascular imaging catheter configured to be positioned within a vessel of a patient; and
a processor configured for communication with the intravascular imaging catheter, wherein the processor is configured to:
receive, from the intravascular imaging catheter, a first intravascular image including the vessel and a reference item;
output, to a display in communication with the processor, the first intravascular image including the vessel and the reference item;
receive a user input to move the displayed reference item from a first position to a second position, wherein the first position comprises a first diameter, wherein the second position comprises a second diameter different from the first diameter;
determine a calibration value based on a difference between the first diameter and the second diameter;
generate, in response to determining the calibration value based on the difference between the first diameter and the second diameter, a second intravascular image of the vessel, wherein the second intravascular image is a transformation of the first intravascular image based on the calibration value; and
output, to the display without conducting a new scan, the second intravascular image of the vessel.
