OCT Tool Explores How Sound Moves Through the Ear

Facebook Twitter LinkedIn Email Comments
A vibrational imaging tool based on optical coherence tomography (OCT) is providing new insight into how the ear receives and processes sound waves. Called OCT vibrography, the tool was built by a team at the Wellman Center for Photomedicine at Massachusetts General Hospital to visualize how sound-induced vibrations travel through the ear. OCT vibrography images the middle ear through the intact eardrum and measures the tiny vibrations within the ear that contribute to sound perception. The researchers reconstructed the motion of ossicular bones in a chinchilla cadaver. Courtesy of the...Read full article
