Optical coherence microscopy with a split-spectrum image reconstruction method for temporal-dynamics contrast-based imaging of intracellular motility
Biomedical researchers use optical coherence microscopy (OCM) for its high resolution in real-time label-free tomographic imaging. However, OCM lacks bioactivity-related functional contrast. We developed an OCM system that can measure changes in intracellular motility (indicating cellular process states) via pixel-wise calculations of intensity fluctuations from metabolic activity of intracellular components. To reduce image noise, the source spectrum is split into five using Gaussian windows with 50% of the full bandwidth. The technique verified that F-actin fiber inhibition by Y-27632 reduces intracellular motility. This finding could be used to search for other intracellular-motility-associated therapeutic strategies for cardiovascular diseases.

Optical coherence tomography (Book Chapter)
Optical coherence tomography (OCT) is a non-invasive optical method that is able to inspect beneath the surface of low-scattering media. OCT retrieves high resolution cross-sectional images employing light, making it possible to observe internal echoes corresponding to an object's structural information. It was first used for optical fiber inspection, but it quickly found use in the medical field, particularly in ophthalmology. It is now applied in a broad spectrum of engineering and medical fields.

Optical Coherence Tomography Angiography for Biomarker Indices in Diabetes (Book Chapter)
Optical coherence tomography angiography (OCTA) visualizes the structure and flow of retinal vasculature using motion contrast. Diabetic retinopathy (DR), commonly present in one-third of the patients with diabetes, is a major microvascular complication of diabetes mellitus caused by retinal ischemia and vascular hyperpermeability. Microvasculature changes, such as foveal avascular zone enlargement and decrease in vascular density of the deep capillary plexus, have been identified in diabetic eyes without clinical retinopathy. OCTA of nonproliferative DR shows morphologically well-defined microaneurysms and intraretinal vascular shunts around perfusion dropouts at the deep capillary plexus level. In proliferative DR, OCTA visualizes detailed features and extent of neovascularization in response to anti-vascular endothelial factor and laser treatment. Diabetes-induced microvascular changes can be quantified by OCTA, and significant correlations have been shown with serum biomarkers r...
