چکیده
The article presents the results of studies melanin effect on recorded signals in laser Doppler flowmetry (LDF) and tissue reflectance oximetry (TO). By investigating properties microvascular blood flow skin oxygenation signals, we have gained new knowledge about race-related differences formation these signals. content intensity LDF TO methods was evaluated, limitations use representatives different ethnic groups were shown.

Inverse Monte Carlo in a multilayered tissue model: merging diffuse reflectance spectroscopy and laser Doppler flowmetry.
The tissue fraction of red blood cells (RBCs) and their oxygenation and speed-resolved perfusion are estimated in absolute units by combining diffuse reflectance spectroscopy (DRS) and laser Doppler flowmetry (LDF). The DRS spectra (450 to 850 nm) are assessed at two source-detector separations (0.4 and 1.2 mm), allowing for a relative calibration routine, whereas LDF spectra are assessed at 1....
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 کاملMicrocirculation assessment using an individualized model for diffuse reflectance spectroscopy and conventional laser Doppler flowmetry.
Microvascular assessment would benefit from co-registration of blood flow and hemoglobin oxygenation dynamics during stimulus response tests. We used a fiber-optic probe for simultaneous recording of white light diffuse reflectance (DRS; 475-850 nm) and laser Doppler flowmetry (LDF; 780 nm) spectra at two source-detector distances (0.4 and 1.2 mm). An inverse Monte Carlo algorithm, based on a m...
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...
