Tissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
متن کاملBlood Flow Measurement by Laser Doppler Method in Orofacial Region
Laser Doppler is a noninvasive, objective, reproducible and painless method for measuring blood flow in tissue microcirculation. This method is based on the Doppler effect, the change in frequency of light reflecting from blood cells in motion. Light from helium-neon laser through optical fibers and probes is directed to the surface of the tissue in which the flow is measured. Light portion is ...
متن کاملContinuous measurement of tissue blood flow by laser-Doppler spectroscopy.
Laser light scattered from tissue in vivo is broadened in line width as a result of the Doppler shift produced by moving red cells in the microcirculation. A feasibility study was carried out to demonstrate use of this effect to measure and monitor tissue blood flow. Light from a helium-neon laser illuminated a 1-mm area of tissue (human skin or rat renal cortex), and the backscattered light wa...
متن کاملMeasurement of Reynolds Stress Distribution in a Fluidic Element by the Laser Doppler Velocimeter
The one-phase flow and the two-phase flow in a fluidic element are investigated by measuring Reynolds stress distributions of the main jets using the laser Doppler velocimeter. In the one-phase flow, a water flow jets from a main nozzle into water and in the two-phase flow, a water fiow jets into air. Some results with the one-phase flow are as follows. When either of the two control ports is c...
متن کاملLaser Doppler measurement of rectal mucosal blood flow.
BACKGROUND Gut mucosal blood flow measurement is used to study a variety of disorders and possibly extrinsic neural function. AIMS To determine optimal measurement criteria and validate this technique as a measure of level of activity of extrinsic autonomic gut innervation. METHODS In 26 healthy volunteers a laser Doppler mucosal probe was applied 10 cm from the anus. Response to inhaled sa...
