Area of Science:

Ophthalmology
Medical Imaging
Computer Vision

Background:

Optical coherence tomography (OCT) is a key imaging technique in ophthalmology.
Different OCT devices provide complementary data, necessitating image registration for combined analysis.
Current registration methods may lack automation or multi-modal compatibility.

Purpose of the Study:

To develop and evaluate a novel automated pipeline for registering multi-modal OCT images from different devices.
To improve the accuracy and efficiency of combining complementary OCT datasets.
To facilitate advanced clinical applications through precise OCT image registration.

Main Methods:

A two-step automated pipeline was developed.
Step 1: Multi-modal 2D en-face registration using deep learning.
Step 2: Z-axis (axial) registration guided by retinal layer segmentation.

Main Results:

The pipeline demonstrated high-quality registration performance.
Mean error for 2D en-face registration was approximately 46 µm.
Mean error for Z-axis registration was 9.59 µm.

Conclusions:

The proposed automated pipeline effectively registers OCT images from different devices.
The method achieves high accuracy in both 2D and Z-axis registration.
This technique holds potential for improving clinical applications, including validation of retinal layer segmentation.
