Depth of penetration of scanning laser Doppler flowmetry in the primate optic nerve.
OBJECTIVES To estimate the measuring depth of the blood flow and to establish the vascular contributions to these measurements with scanning laser Doppler flowmetry (SLDF) of the primate anterior optic nerve. METHODS Optic nerve blood flow in each eye of 8 monkeys was measured using SLDF before and following surgical occlusion of the central retinal artery (n = 4) or posterior ciliary arterie...
متن کاملMeasurement depth and volume in laser Doppler flowmetry.
A new method for estimating the measurement depth and volume in laser Doppler flowmetry (LDF) is presented. The method is based on Monte Carlo simulations of light propagation in tissue. The contribution from each individual Doppler shift is calculated and thereby multiple Doppler shifts are handled correctly. Different LDF setups for both probe based (0.0, 0.25, 0.5, and 1.2 mm source-detector...
متن کاملEvaluation of Carpal Tunnel Syndrome by Laser Doppler Flowmetry
Background:Autonomic disturbance can leads to blood flow changes that can be studied by various methods. Objective: To assess the blood flow changes in patients with severe carpal tunnel syndrome by laser Doppler flowmetry Methods:Ten patients with severe unilateral carpal tunnel syndrome confirmed by electrodiagnostic examination enrolled in this study. Patients comprised one man and nine wom...
متن کاملQuantitative Laser Doppler Flowmetry
vii-Abstract Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. The first i...
متن کاملConfocal scanning laser Doppler flowmetry in the rat retina: origin of flow signals and dependence on scan depth.
OBJECTIVE To investigate the origin of signals from scanning laser Doppler flowmetry (SLDF) and the influence of axial scan depth on the measurement of blood flow in the rat retina. METHODS We performed SLDF in 5 adult Sprague-Dawley rats using a specially modified Heidelberg retina flowmeter. Axial scans were obtained from +2 diopters (D) to -3 D (in steps of 0.25 D) or from +1 D to -2 D (in...
