Currently laryngeal cancer can only be diagnosed with biopsies which are invasive, permanently damaging, and can miss cancerous tissue. Optical Coherence Tomography (OCT) is an imaging technique that non-invasively images several millimeters into tissue to seek structural abnormalities, which can indicate cancer. We will design and construct an OCT device for attachment to a laryngoscope that will image two-dimensional cross-sections in the larynx, for the purpose of diagnosing laryngeal cancer in its early stages.
