35 Claims

1. An intraluminal imaging system, comprising:

an intraluminal imaging catheter or guidewire configured to be positioned within a body lumen of a patient; and

a processor circuit in communication with the intraluminal imaging catheter or guidewire, wherein the processor circuit is configured to:

receive, from the intraluminal imaging catheter or guidewire, a first intraluminal image of the body lumen;

compute a dimension of an anatomical feature of the body lumen in the first intraluminal image;

compute a scaling factor for the first intraluminal image based on the computed dimension of the anatomical feature and a reference dimension for the anatomical feature, wherein the computed dimension and the reference dimension are each a diameter;

scale the first intraluminal image by the scaling factor; and

output the scaled first intraluminal image to a display in communication with the processor circuit.
