AI Technical Summary

Technical Problem

Current intraoperative OCT navigation systems for ophthalmic surgical microscopes are limited to two-dimensional imaging, which fails to display image details and can lead to display leakage.

Method used

Implementing a method and system that acquires three-dimensional OCT original scan data using a galvanometer scanner, processes it to obtain a first A-scan signal, and displays a three-dimensional OCT image, enhancing the display effect by employing various scanning modes and signal processing techniques.

Benefits of technology

Enables real-time three-dimensional OCT navigation, improving the display quality and detail presentation during ophthalmic surgeries by reducing data transmission costs and enhancing image clarity and stability.

Abstract

This disclosure provides an intraoperative OCT navigation method, system, and ophthalmic surgical microscope for use in ophthalmic surgical microscopes. The system comprises a galvanometer scanner (410) for acquiring original 3D OCT scanning data of the patient's eye; a signal processing device (420) for signal processing the acquired original 3D OCT scanning data and acquiring a first A-type scanning signal of the OCT image; and a display device (430) for displaying the 3D OCT image based on the first A-type scanning signal of the acquired OCT image. The ophthalmic surgical microscope (500) comprises the system.
