Learning Objectives: 1. To review limitations in current imaging 2. To review the principles of high frequency ultrasound 3. To review the principles of optical coherence imaging 4. To illustrate uses of these technologies in otology.

Current imaging tools for the ear are limited in their resolution, and also have significant downsides, such as radiation, or interaction with metallic objects.

We have been developing new technologies based on very high frequency ultrasound (>40Mhz), and optical coherence tomography (OCT). These technologies have been developed in-house in our labs. We will present the present capacity of these devices, including in-vitro temporal bone measurements of anatomy, simulated pathology, and vibration measurements, as well as tracking cochlear implants during insertion. We also have in-vivo measurements using the OCT device. We will present possible uses, both in the middle ear, and in the cochlea and inner ear.
