Algorithm for assessing retinal fluid volume using OCT/OCTA
SummaryMeasurement of retinal fluid volume could improve diagnosis and tracking of diabetic macular edema (DME); however, current methods rely on two-dimensional measurements, which have limited accuracy. The current technology uses volumetric OCT/OCT angiography scans to provide a three-dimensional and more accurate retinal fluid volume, potentially...

Quantification of Vascular Abnormality with OCT Angiography
SummaryCurrent OCT techniques are limited in their ability to accurately detect vasculature changes, and patients with retinal vascular diseases often require more invasive intravenous contrast dye-based angiography procedures. The current technology is an OCT-based non-injection, dye-free method that allows for 3D visualization of superimposed structural...

Self-tracking real-time high-resolution wide-field OCT angiography (OCTA)
SummaryOptical coherence tomographic angiography (OCTA) provides superior resolution and volumetric data compared to fluorescein angiography, but this 3D technology requires motion artifact compensation caused by movements during the scan. Oregon Health & Science University researchers have developed a method to suppress motion artifacts caused...

A fast and robust standard-deviation based method for bulk-motion compensation in phase-based functional OCT
Standard deviation phase compensation for OCTA and Doppler OCTThis invention involves a novel bulk motion compensation method for phase-based functional OCT. The two widely used phase compensation methods are the “average” (AVG) method and the “histogram” (HIST) method, wherein the latter estimates the vessel shadow artifact...
