Current pulse oximeters become unreliable at low oxygen saturations because the influence
of physiological artifacts that are not measured independently such as the blood content of …

Reconstructing deep-tissue images in real time using spectrophotometric data from optically
diffusing thick tissues has been problematic. Continuous wave applications (eg, pulse …

We have developed a multichannel photon counting instrument for near infrared spatially
resolved spectroscopy. The instrument uses two laser diodes at 780 and 830 nm. The two …

An instrument for monitoring backscattered light from living tissue, in two wavelengths, is
described. The backscattered light data is used for the in vivo determination of the blood's …

We present a multi-channel, multi-distance broadband near-infrared spectroscopy (NIRS)
system with the capability of measuring changes in haemoglobin concentrations (Δ [HbO_2] …

Vibrating probe technology has enabled scientific investigations that have expanded our
knowledge of form and function in biology, but the emergence of new fields of cytomics and …

BACKGROUND: As the use of pulse oximeters increases, the needs for higher performance
and wider applicability of pulse oximetry have increased. To realize the full potential of pulse …

A novel technique for the noninvasive measurement of tissue optical properties
simultaneously at all visible and near-infrared wavelengths is presented. The technique is …

We present a compact, fast, and versatile fiber-optic probe system for real-time
determination of tissue optical properties from spatially resolved continuous-wave diffuse …

A new clinical tissue oxygenation monitor, the NIRO-300, has been developed. In addition to
monitoring changes in hemoglobin concentration and redox state of cytochrome oxidase …
