三維成像技術讓助聽器安裝只需一二分鐘時間

重點摘要:

Hart has patented a new way of scanning the ear canal with 3D imaging technology — a process that is much faster, easier, and more accurate than the plaster-mold technique. He plans to market the technology to hearing-aid manufacturers first, but believes it could also be useful to build fitted earphones for MP3 music players, or custom-fit earplugs for military personnel and other people who work in noisy environments.

With the new MIT system, a very stretchy, balloon-like membrane is inserted into the ear canal and inflated to take the shape of the canal. The membrane is filled with a fluorescent dye that can be imaged with a tiny fiber-optic camera inside the balloon. Scanning the canal takes only a few seconds, and the entire fitting process takes only a minute or two.
