Tissue oxygenation sensing at a few millimeters deep is useful for surgical and
postoperative management. However, the measurement sensitivity at each depth and the …

In this paper, the influences of overlying tissue and detecting distance between the source
and the detector on the measurement of a tissue oximeter were discussed. The signal-noise …

In this paper, the biological tissue oxygen saturation (rSO2) is obtained non-invasively and
in real time based on near infrared spectroscopy (NIRS) using two emitting wavelengths and …

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 …

We examined the influence of probe‐tissue distance on the relationship between the deep
tissue absorption coefficient and the spatial profile of light intensity by Monte Carlo …

Significance Continuous wave near infrared spectroscopy (CW-NIRS) is widely exploited in
clinics to estimate skeletal muscles and brain cortex oxygenation. Spatially resolved …

Photonify's tissue spectrometer uses Near-Infrared Spectroscopy for real-time, noninvasive
measurement of hemoglobin concentration and oxygen saturation [SO 2] of biological …

The inhomogeneity of tissue structure greatly affects the sensitivity of tissue oxygenation
measurement by reflectance NIRS. We have proposed a method for correcting the influence …

Background: Flap monitoring in reconstructive surgery is particularly important because flap
failure is a dramatic event for the patient and for the medical team. Noninvasive deep tissue …
