1. An intraluminal imaging system, comprising:
an intraluminal imaging catheter comprising an imaging sensor disposed at a single location along a length of the intraluminal imaging catheter; and
a processor circuit configured for communication with the intraluminal imaging catheter, wherein the processor circuit is configured to:
control the imaging sensor to obtain a plurality of intraluminal images during manual movement of the intraluminal imaging catheter by a user through a body lumen of a patient, wherein the plurality of intraluminal images comprises a first intraluminal image obtained by the imaging sensor and a second intraluminal image obtained by the imaging sensor;
perform image processing to identify an anatomical feature in the first intraluminal image and in the second intraluminal image;
determine, based on the image processing, a change in a visual appearance of the anatomical feature between the first intraluminal image and the second intraluminal image, wherein the change in the visual appearance of the anatomical feature corresponds to:
the first intraluminal image being obtained by the imaging sensor at a first position within the body lumen during the manual movement of the intraluminal imaging catheter by the user; and
the second intraluminal image being obtained by the imaging sensor at a different, second position within the body lumen during the manual movement of the intraluminal imaging catheter by the user;
determine, in real time during the manual movement of the intraluminal imaging catheter by the user, a longitudinal translation speed of the intraluminal imaging catheter using the plurality of intraluminal images obtained by the imaging sensor, wherein the determination of the longitudinal translation speed is based on:
the change in the visual appearance of the anatomical feature between the first intraluminal image and the second intraluminal image; and
a known time interval between the first intraluminal image and the second intraluminal image; and
output, to a display in communication with the processor circuit, a screen display to the user, wherein the screen display includes a speed indicator based on the longitudinal translation speed.
