Laser-Doppler flowmetry reveals rapid perfusion changes in

Laser Doppler flowmetry (LDF) is a non-invasive method for the continuous measurement of microvascular blood perfusion in a variety of tissue types. Blood perfusion (blood flow) is estimated by illuminating a tissue sample with single-frequency light and processing the frequency distribution of the backscattered light. Specifically for human studies, our single-channel Laser Doppler FlowMeter Laser Doppler Flowmetry Optical Imaging Based on Intrinsic Signals. Nader Pouratian, Arthur W. Toga, in Brain Mapping: The Methods (Second Optical methods for assessing skin flap survival. The LDF was developed in the late 1970s for measuring the blood flow Diagnosis.

Laser Doppler flowmetry (LDF) is now commonly used in clinical research to monitor microvascular blood flow. However, the dependence of the LDF signal on the microvascular architecture is still unknown. That is why we propose a new laser Doppler flowmeter for depth dependent monitoring of skin microvascular perfusion. This new laser Doppler flowmeter combines for the first time, in a device Laser Doppler Flowmeter, supplied by Moor Instruments, used in various techniques.

Baab DA, Oberg PA. Laser Doppler measurement of gingival blood flow in dogs with increasing and decreasing inflammation. Abstract: An instrument for measurement of tissue blood flow based on the laser Doppler principle was evaluated using a fluid model. A unique and linear relationship between flowmeter response and flux of red cells was demonstrated with red cell velocities and volume fractions within the normal physiological range of the microcirculatory network of the skin. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light. The LaserFlow is ideal for a broad range of wastewater monitoring applications.
