The cardiac cycle related pulsatile behavior of the absorption and scattering coefficients of
diffuse light and the corresponding alterations in hemoglobin concentrations in the human …

Human bone blood flow, mean blood speed and the number of moving red blood cells were
assessed (in arbitrary units), as a function of time, during one cardiac cycle. The …

Publisher Summary Methods of absorption photometry are sensitive enough to measure in
vivo natural pigments such as hemoglobin, myoglobin, and cytochromes that participate in …

Pulsed-photoacoustic spectroscopy in the near IR portion of the optical spectrum was used
as a local technique for quantitative monitoring of tissue hemoglobin concentration and its …

PPG volumetric model is frequently adopted to explain the pulsatile nature of optical
response for arterial pulsation. In this article we show that the pulsatile fluctuation of optical …

Hemoglobin (Hb), as one of main components of blood, has a unique quaternary structure.
Its release of oxygen is controlled by oxygen partial pressure (PO 2). We investigate the …

A photoplethysmographic (PPG) technique to assess blood flow in bone tissue has been
developed and tested. The signal detected by the PPG consists of a constant-level (DC) …

Photon migration in highly scattering tissues such as muscle and brain gives optical
pathlengths that are dependent upon absorption and scattering parameters, μ a μ s' …

Reduced scattering and absorption coefficients of piglet head were measured in-vivo by
analyzing the observed temporal responses based on the diffusion theory. The reduced …
