Anatomical optical coherence tomography: a safe and effective tool for quantitative long-term monitoring of upper airway size and shape

Anatomical optical coherence tomography (aOCT) is an endoscopic optical technique that enables continuous, quantitative assessment of hollow organ size and shape in three dimensions. It is a powerful alternative to X-ray computed tomography, magnetic resonance imaging, and video endoscopy for the assessment of gross hollow-organ anatomy. This paper reviews our instrument and its application to the upper and lower airway, and includes a number of new results.
