We have developed an anatomical optical coherence tomography system for imaging the human upper airway in vivo. We describe an example of clinical research currently underway with this system; the ability to measure the change in airway dimensions due to anatomical position. Although the system imaging range is well-matched to a typical airway, we have observed a range of conditions which preclude the capture of full airway profiles in a small number of cases. Here, we demonstrate an improvement in the system range which allows us to successfully measure a larger percentage of subjects.
