Abstract
A system for imaging a body lumen includes a controller and a display. The controller is configured to connect to a proximal end of a catheter having an optical fiber extending along the length of an elongate catheter body. The controller is further configured to rotate a distal end of the optical fiber from a location near a proximal end of the elongate catheter body, acquire optical coherence tomography (OCT) images using the optical fiber as the distal end of the optical fiber rotates, and determine a rotational lag of the distal end of the optical fiber. The display is configured to display one or more OCT images corrected for the rotational lag.
