Intraoperative FD-OCT of the pediatric airway. A 0.7 mm OD OCT probe (75–80 cm length) is connected to a combined rotational motor and dual-motor stage for linear pullback. The probe, housed in a transparent fluorinated ethylenepropylene (FEP) sheath, is inserted through a Y-connector and advanced inside the endotracheal tube. The combined motors simultaneously rotate and retract the probe through the upper airway as OCT signal is reflected at 90° into the tissue. ETT = endotracheal tube.
