Fractal dimensions of laser doppler flowmetry time series
Medical Engineering & Physics, 2002Laser Doppler flowmetry (LDF) provides a non-invasive method of assessing cutaneous perfusion. As the microvasculature under the probe is not defined the measured flux cannot be given absolute units, but the technique has nevertheless proved valuable for assessing relative changes in perfusion in response to physiological stress.

History of Laser-Doppler Blood Flowmetry
1990The best-known applications of the Doppler principle in biology and medicine are a series of different techniques for assessing blood flow from the Doppler shift that sound waves experience when they travel through the blood flowing in a relatively large blood vessel.

Instant of vascular occlusion defined with laser-Doppler flowmetry
Journal of Applied Physiology, 1992Derivation of capillary pressure from tracings postarterial (AO) or -venous (VO) occlusion requires back extrapolation to an instant near the time of occlusion. This instant is difficult to identify because of pressure artifacts created by the occlusion maneuver.

Clinical Applicability of Laser Doppler Flowmetry in Neurosurgery
1994Different methods for the measurement of cerebral perfusion must be distinguished: methods for discontinuous measurement of regional cerebral perfusion and methods for continuous measurement of microflow. Only thermoclearance and laser Doppler flowmetry (LDF) can be used during surgery or in critically ill patients on the intensive care unit, and both ...
