Quantitative 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...
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 کاملLaser Doppler flowmetry in manual medicine research.
Laser Doppler flowmetry (LDF) is commonly used in combination with reactivity tests to noninvasively evaluate skin sympathetic nerve activity and skin microvascular function. In manual medicine research, LDF has been used as a marker for global peripheral sympathetic nervous system function, but these results should be considered with caution because skin sympathetic nerve activity physiology i...
متن کاملLaser Doppler Flowmetry - a Theoretical Framework
Laser Doppler Flowmetry (LDF) is a non-invasive method to estimate the blood perfusion in the microcirculation. The method was first introduced over 30 years ago and has undergone a continuous development since. This work presents a thorough theoretical framework of the technique. It is described in detail how the laser light interacts with the tissue and moving red blood cells, how the light f...
