Technology

Measuring the ear canal accurately via the traditional ear mold impression process is often time-consuming, inefficient, messy and uncomfortable.  Hearing professionals and manufacturers have long anticipated a solution that rapidly captures ear canal shape in a digital image that can be sent electronically, reducing the number of steps required to produce a custom ear device.  Based on breakthrough 3D scanning technology that originated in the laboratories of Massachusetts Institute of Technology, Lantos Technologies has created a complete, digital solution for inspecting and imaging the ear canal.

Lantos Technologies’ AURA 3D Ear Scanning System creates a digital representation of the ear canal. The revolutionary technology was developed at the Massachusetts Institute of Technology. Using the intensity measurement of two different wavelength bands of fluorescent light as they travel through an absorbing medium, capturing images and stitching them together with elegant algorithms, the system generates a highly accurate 3D map. This novel imaging approach enables the ability to measure changes in ear canal shape that accompany body movements such as opening the mouth, producing a representation of the ear canal.

The AURA™ 3D Ear Scanning System is composed of a hand-held scanner with retractable probe, a single-patient disposable, and imaging software with an intuitive user interface –which integrate seamlessly in the audiology practice workflow. First, as a video otoscope, the hearing professional enters the ear canal, visualizing the canal clearly on the monitor. With a press of a button, the conforming membrane is filled with the absorbing medium causing the membrane to expand and conform to the shape of the ear canal. The scope then advances and retracts to generate a 3D image of the ear canal in real time. The entire scan takes less than 60 seconds. Scanning data is then processed and sent electronically by computer to the manufacturer anywhere in the world instantaneously, where the custom in ear device may be created.
