Unsupervised 3D Retinal Vessel Segmentation

[2021 MICCAI] LIFE: A Generalizable Autodidactic Pipeline for 3D OCT-A Vessel Segmentation


Method

In this work, we proposed to conduct the self-fusion algorithm on the neighboring depth images of 3D retinal OCT-A to create an auxiliary modality with cleaner vessels. Subsequently, we implement a dual-Unet architecture to map each en-face slide to its self-fusion counterpart. The latent image turns out to be a well-enhanced angiography that can be binarized with Otsu method.
