INSTRUMENT DEPTH TRACKING FOR OCT-GUIDED PROCEDURES

摘要

Systems and methods are provided for tracking a depth of a surgical instrument in an optical coherence tomography (OCT) guided surgical procedure. An OCT device (12) is configured to image a region of interest (14) to provide OCT data. A scan processor (16) is configured to determine a relative position of the instrument (18) and a target (20) within the region of interest from at least the OCT data, where the instrument is one of in front of the target, within the target, or below the target. A feedback element (22) is configured to communicate the relative position of the instrument and the target to a user in a human comprehensible form.
