Applying 3D Upper Airway Ultrasound Imaging to Clinical Diagnosis of Obstructive Sleep Apnea

Purpose: To “see” the airway: how it collapses during snoring for our patients with obstructive sleep apnea remains a challenge. At Stanford, we started a study using ultrasound imaging to “see” your airway in a non-invasive manner without radiation.

PI: Clete Kushida, MD, PhD / Stanley Liu, MD, DDS

Study status: Open, enrollment ongoing
