Abstract

We report neural network-based rapid reconstruction of swept-source OCT (SS-OCT) images using undersampled spectral data. We trained and blindly tested a deep neural network using mouse embryo samples imaged by an SS-OCT system. Using >3-fold undersampled spectral data per A-line, the trained neural network can blindly remove spatial aliasing artifacts due to spectral undersampling, presenting a very good match to the images reconstructed using the full spectral data. This method can be integrated with various swept-source or spectral domain OCT systems to potentially improve the 3D imaging speed without a sacrifice in resolution or signal-to-noise of the reconstructed images.
