Self-supervised model-informed deep learning for low-SNR SS-OCT domain transformation. [PDF]

Sci Rep
Abstract This article introduces a novel deep-learning based framework, Super-resolution/Denosing network (SDNet), for simultaneous denoising and super-resolution of swept-source optical coherence tomography (SS-OCT) images. The novelty of this work lies in the hybrid integration of data-driven deep-learning with a model-informed noise ...

Evaluating the persistence of large choroidal hypertransmission defects using SS-OCT imaging. [PDF]

Exp Eye Res
In age-related macular degeneration (AMD), large choroidal hypertransmission defects (hyperTDs) are identified on en face optical coherence tomography (OCT) images as bright lesions measuring at least 250 μm in greatest linear dimension (GLD). These choroidal hyperTDs arise from focal attenuation or loss of the retinal pigment epithelium (RPE).

Accuracy assessment of three-dimensional abutment tooth data construction using swept-source optical coherence tomography. [PDF]

PLoS ONE
A limitation of widely used intraoral scanners (IOSs) is their inability to capture finish lines at the subgingival marginal area, as they only extract surface information.

Comparison of choroidal thickness measurements between spectral domain optical coherence tomography and swept source optical coherence tomography in children

Scientific Reports, 2021
Choroidal thickness is associated with many ocular conditions, interchangeability among different generations of optical coherence tomography is therefore important for both research purpose and clinical application.
