Laser Doppler flowmetry to assess myocardial microcirculation [PDF]
Cardiology Journal, 2020 Several different methods enable the study peripheral microcirculation. Among them, non-invasive laser Doppler flowmetry (LDF) is routinely used to assess microvascular function by quantifying rapid changes in skin blood flow in response to a given pharmacological or mechanical stimulus [1]. Owing to its accessibility, peripheral microvascular function

Measurement depth and volume in laser Doppler flowmetry
Microvascular Research, 2009 A new method for estimating the measurement depth and volume in laser Doppler flowmetry (LDF) is presented. The method is based on Monte Carlo simulations of light propagation in tissue. The contribution from each individual Doppler shift is calculated and thereby multiple Doppler shifts are handled correctly. Different LDF setups for both probe based (

Machine learning in multiexposure laser speckle contrast imaging can replace conventional laser Doppler flowmetry. [PDF]
J Biomed Opt, 2019 . Laser speckle contrast imaging (LSCI) enables video rate imaging of blood flow. However, its relation to tissue blood perfusion is nonlinear and depends strongly on exposure time.
