Abstract

We present an early release of our study utilizing a fiber-based Optical Coherence Tomography (OCT) probe to acquire 3D images of the airway in sleep apnea patients. The probe, with a 1.3mm diameter, navigates from the nasal cavity to the vocal cords while rotating within a transparent protective sheath. Long-range OCT imaging (2-30mm) enables comprehensive airway visualization. Our approach facilitates airflow dynamic analysis, aiding in the identification of critical regions prone to collapse during sleep. This non-invasive technique promises to revolutionize sleep apnea diagnostics and personalized treatment planning, offering substantial benefits to patient care.
