Abstract
A detector for characterizing at least one of a middle ear fluid and a middle ear biofilm includes a handheld probe outputting near-infrared and visible light, an OCT system to obtain A-scans at a plurality of positions on a tympanic membrane, and a camera to obtain surface sub-images at the plurality of positions. A-scans and surface sub-images are synchronized and the surface sub-images are mosaicked to generate a surface image of the tympanic membrane. Cross-sectional scan images or a thickness map are generated from the synchronized A-scans and segmented to extract a plurality of specified features. The specified features are then classified to characterize at least one of the middle ear fluid and the middle ear biofilm. The detector, including handheld probe with camera, OCT system, and a laptop computer, is sized to fit into a handheld, portable, compact, foam-padded briefcase weighing less than 10 kg.
