Lantos Technologies, Inc. announced that it has received clearance from the United States Food & Drug Administration (FDA) to market the Lantos 3D Ear Scanning System.
The Lantos 3D Ear Scanning System is composed of a portable handheld scanner with a video otoscope for visualization and navigation of the ear canal. The small, hand-held portable scanner using Lantos' patented dual-wavelength algorithm technology is the first platform capable of measuring direct ear scans as well as ear canal dynamics and tissue elasticity.
Getting useful sound amplification depends on a tight fit between hearing aid and ear canal. Patients usually have to spend about an hour with an audiologist, who fills the patient's ear canal with a resin-based substance to generate an impression. After about 15 minutes, the gel solidifies and forms a mold of the ear canal. Removal of the mold may not only be uncomfortable, but may also cause distortion of the impression's shape. The entire process is time consuming and inefficient.
Lantos Technologies, an M.I.T. spin out, developed a new way of scanning the ear canal with 3D imaging technology. With the new system a membrane-based consumable is inserted into the ear canal and expands to conform to the ear canal anatomy. Using the intensity measurement of two different wavelength bands of fluorescent light as they travel through the membreane, capturing images and stictching them together with algorithms, the system generates a highly accurate 3D map.
With this system, scanning the canal takes only a few seconds, and the entire fitting process takes only a minute or two. The image can rapidly be transferred electronically in a format applicable to any device manufacturer.
According to Jeffrey Leathe, CEO and Chairman of the Board at Lantos, "The straightforward process of obtaining a 3D representation of the ear canal by our system provides opportunities to improve efficiencies across the hearing device value chain. We are excited to receive FDA 510(k) clearance – it demonstrates our commitment to offer innovative and disruptive technology that is both safe and efficacious".
The 3D Ear Scanning System can be used in hearing aid, consumer audio, industrial noise protection, military and communication markets. It will be commercially available later this year.

Very soon there will be an easier way to direct scan the ear canal and construct a 3D model. The only thing needed is a camera (video otoscope), which captures video images of the ear canal. Then a 3D program converts the images to a 3D model almost in real time. Nothing else except the camera is introduced into the ear canal - no balloon, no laser etc. Could it be easier and smarter?
