Rationale: Peripheral artery disease (PAD) is common among the elderly and increases the risk of cardiovascular events, disability and death. PAD course and outcomes depend not only on the condition of macrovasculature but also on the tissue perfusio

Abstract Pre-processing of the photoplethysmography (PPG) signal plays an important role in the analysis of the pulse wave signal. The task of pre-processing is to remove noise from the PPG signal, as well as to transmit the signal without any distor

This study aimed to examine the mechanisms of the photoplethysmography (PPG) signal formation using Monte Carlo simulations of light transport in biological tissues and experimental observations. Based on a three-layer skin model in backscattering ge

Since UV radiation is capable of causing skin erythema, there is a risk of damage during in vivo UV spectroscopy of skin. In particular, the conventional estimation of radiation dose indicates the impossibility of conducting such studies when using f

Currently, there is enough data to suggest a significant role of microcirculation abnormalities in the pathophysiology of COVID-19. However, no clinical studies on noninvasive assessment of blood microcirculation in patients with the new coronavirus

Laser-based medical techniques for evaluating blood flow (BF), such as laser Doppler flowmetry, laser speckle contrast imaging, etc., are known, but expensive and have some disadvantages. Recently, we have proposed a new technique—incoherent optica
