Abstract

Systems and methods of optical coherence tomography. The systems may include a source of optical radiation, an elongate catheter body, an optical fiber, a handle, a detector and a processor. The optical fiber may extend from a proximal end to a distal end of the elongate catheter body, and be fixed to the distal end of the elongate catheter body. The optical fiber may provide a common path for radiation reflected from a reference and a target. The handle may be attached to the proximal end of the elongate catheter body and be configured to allow rotation of the elongate catheter body and the optical fiber relative to the handle about a longitudinal axis. The detector may be configured to receive the radiation reflected from the reference and the target. The processor may be configured to generate an image of the target based upon the radiation received by the detector.
