Claim 9:
10. An imaging device for imaging coiled tubing (CT), comprising:
a housing having two openings at opposing ends and a cavity therebetween, the opening and the cavity being arranged to axially accommodate and pass through a length of coiled tubing;
a radial ultrasound array facing radially-inward towards the cavity and divergently focused at the surface of the CT; and
a processor programmed to:
capture a first image of the CT with the ultrasound array in a first frame;
capture a second image of the CT with the ultrasound array at a subsequent frame, wherein the first image and the second image are partly overlapping; and
compare the first image and the second image to determine an amount of shift of the same features in the first image and the second image, and estimate an amount of movement of the CT through the imaging device.
