Imaging pulsatile retinal blood flow in human eye.
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 ...
متن کاملPulsatile Blood Flow in Human Carotid Bifurcation
The purpose of this paper is to present a numerical simulation system for blood flow in the carotid artery bifurcation and its validation using experimental data collected in clinical practice. Blood flow is described by the incompressible Navier-Stokes equations and the simulation is carried out under pulsatile conditions using inlet velocities given by a flow wave form obtained by ultrasound ...
متن کاملPulsatile Blood Flow
In addition to many overly restrictive simplifications of this type, the text offers some extraordinary and equally arresting therapeutic suggestions. In 1964, it is intriguing to discover that relief in pericarditis "is often obtained from the application of four or five leeches over the praecordium," that extract of ox gall may help the symptoms of acute hepatitis, and that "Kaolin poultices ...
متن کاملHolographic laser Doppler imaging of pulsatile blood flow.
We report on wide-field imaging of pulsatile motion induced by blood flow using heterodyne holographic interferometry on the thumb of a healthy volunteer, in real time. Optical Doppler images were measured with green laser light by a frequency-shifted Mach-Zehnder interferometer in off-axis configuration. The recorded optical signal was linked to local instantaneous out-of-plane motion of the s...
متن کاملPulsatile Ocular Blood Flow in Healthy Koreans
PURPOSE To determine the normal reference range of pulsatile ocular blood flow (POBF) values in healthy Korean subjects and to find out the factors that may affect them. METHODS A total of 280 eyes of 280 normal subjects were included in this study. Best corrected visual acuity (BCVA), intraocular pressure (IOP), axial length, POBF, systemic blood pressure, and pulse rate were measured. The m...
