Imaging Theory

OCT image reconstruction

The topic of Image reconstruction plays an important role in OCT community. New reconstruction methods are desired to improve image quality or axial resolution of OCT images.

We proposed a GPU accelerated B-scan based iterative method to improve the reconstruction speed and image quality for OCT image reconstruction.

Monte Carlo Simulation

Monte Carlo (MC) method, one of the most popular numerical tools used in biophotonics, has long been acknowledged as the gold standard for theoretically investigating the light-tissue interaction.

We present our latest advances in the MC-based studies of Optical Coherence Tomography (OCT) including the image formation theory, spectroscopic OCT, wavelength-dependent scattering, and some inverse problems.

Retina Segmentation

Segmenting the stratified structure of human retina is of great significance in clinical settings for disease diagnosis and preventions.

We devised a technique to incorporate the established medical domain knowledge into our segmentation algorithm with the aid of a graph convolutional network.

Shadow Inpainting

Removing shadows cast by blood vessels in retinal optical coherence tomography (OCT) images is critical for accurate and robust machine analysis and clinical diagnosis.

We proposed a multi-scale sparse representation-based method with the aid of a super resolution network for shadow removal in OCT images.

Holographic Display

Fourier-inspired module

Holographic displays are expected to become the promising technologies for next-generation virtual reality (VR) and augmented reality (AR) optical devices.

We propose a Fourier-inspired neural module, which can be easily integrated into different CGH frameworks and significantly enhance the quality of reconstructed images.
