Using time-resolved spectroscopy, we have developed an experimental approach to obtain
the absolute changes in concentration in the scattering medium of living tissues. The time …

Abstract The time-resolved Beer-Lambert law proposed for oxygen monitoring using pulsed
light was extended to the non-time-resolved case in a scattered medium such as living …

Near infrared spectroscopy is a very useful tool for monitoring the oxygen saturation of living
tissue noninvasively. We can calculate the hemoglobin oxygen saturation within tissue …

The recent development of near-infrared time-and frequency-resolved tissue spectroscopy
techniques to probe tissue oxygenation and tissue oxygenation kinetics has led to the need …

We have developed a three-wavelength (759,797, and 833 nm) time-resolved spectroscopy
(TRS) system as a tissue oxygenation monitor employing a time-correlated single photon …

Analysing transmitted light at 700 and 730 nm, we found a linear relationship between the
blood concentration and the absorbance change in perfused hindlimb of rat when …

We have designed and constructed a near-infrared spectrometer for the non-invasive optical
study of biological tissue. This instrument works in the frequency-domain and employs …

We developed a compact dual-wavelength multichannel tissue oximeter based on the time-
correlated single-photon counting (TCSPC) technique. The light sources are two pulsed …

A portable tissue oximeter that uses light-emitting diodes and two-wavelength near infrared
spectroscopy has been developed. The tissue oximeter is compact enough to be portable …

The ability to quantify the contributions of hemoglobin (Hb) and myoglobin (Mb) to in vivo
optical spectra has many applications for clinical and research use such as noninvasive …
