Method And System For Tracking Of Acoustic Vibrations Using Optical Coherence Tomography
Patent No. EP4185189 (titled "Method And System For Tracking Of Acoustic Vibrations Using Optical Coherence Tomography") was filed by Acoustic Insight on Jul 23, 2021. The application was issued on Nov 5, 2025.
Patent Summary
This method tracks vibrations (V) of a middle or inner ear structural element (94) using a measurement system comprising an acoustic source (1), an OCT device (2), and an optical tracking system (3). The acoustic source generates a stimulus (S) to induce vibrations. The OCT device measures a measurement signal (21) containing vibrographic information along a measurement direction (M). Simultaneously, the tracking system measures a tracking signal (31) representing displacements in at least one tracking direction (T) perpendicular to (M). The tracking signal is used to adjust the measurement signal, which may involve post-processing correction, real-time OCT device adaptation to compensate for displacements, or discarding signals exceeding a displacement threshold.
