AI Article Synopsis
- A functional Fourier domain optical coherence tomography (OCT) instrument was developed for imaging blood flow in the human retina, focusing on the pulsatile nature of this flow.
- An advanced phase-resolved algorithm was introduced to minimize motion artifacts that can affect image quality.
- The study also evaluated the reliability of measuring the resistance index by conducting 14 assessments on two blood vessels in two healthy individuals.
Article Abstract
A functional Fourier domain optical coherence tomography instrument offering spectral Doppler imaging of in vivo pulsatile human retinal blood flow was constructed. An improved phase-resolved algorithm was developed to correct bulk motion artifacts. Spectral Doppler imaging provides complementary temporal flow information to the spatially distributed flow information of the color Doppler image by providing direct visualization of the Doppler spectrum of the flow whose pattern can be further quantified with various velocity envelope curves and their corresponding flow indices. The coefficient of repeatability on resistance index measurement was assessed by analyzing 14 measurements on two vessels within two normal subjects.
