Deep learning restores 3D retinal microvasculature from OCTA scans

Researchers have developed a novel deep learning algorithm to reconstruct the intricate three-dimensional microvasculature of the retina from single OCT Angiography (OCTA) volumes. This method utilizes an EfficientNet-B5 encoder and a specialized decoder to predict a restored middle B-frame from three adjacent frames, addressing limitations in existing OCTA processing techniques that often overlook the full vascular architecture. The algorithm demonstrated significant improvements in image quality, with PSNR and SSIM scores substantially higher than original single OCTA volumes, and notably enhanced microvascular fidelity in both 2D and 3D reconstructions.
